摘要： A method and apparatus for determining operating modes in a receiver is described herein. A delay searcher in the receiver detects a signal image in the received signal. When the receiver is a RAKE receiver, a plurality of RAKE fingers coherently combine time-shifted versions of the received signal at different delays. Alternatively, when the receiver is a chip equalization receiver, an FIR filter coherently pre-combines the signal images in the received signal. A processor determines delays. In particular, the processor generates a first signal quality metric for a single-delay receiver mode, and generates a second signal quality metric for a multi-delay receiver mode. Based on a comparison of the first and second signal quality metrics, the processor selects the single-delay or the multi-delay receiver mode for processing the signal image.

摘要： A wireless communication device or system generates transmit power control feedback for a received power control channel by determining a command error rate (CER), or by identifying a target signal quality for the power control channel according to a defined signal-quality-to-CER mapping function. Generally, the power control channel does not include error-coded data to use for CER estimation. However, in one embodiment, the channel does include known reference bits that are evaluated for CER estimation, with the estimated CER used to set the signal quality target for inner loop power control. In other embodiments, a computed reception error probability is used to identify a CER estimate according to a defined probability-to-CER mapping function. By way of non-limiting example, these embodiments may be used to provide power control feedback for power control commands transmitted on a Fractional Dedicated Physical Channel in WCDMA systems.

摘要： A receiver circuit suppre ses effects of "benign" impairment from the calculation of received signal quality estimates, such that the estimate depends primarily on the effects of non-benign impairment. For example, a received signal may be subject to same-cell and other cell interference plus noise, which is generally modeled using a Gaussian distribution, and also may be due to certain forms of self-interference, such as quadrature phase interference arising from imperfect de-rotation of the pilot samples used to generate channel estimates for the received signal. Such interference generally takes on a distribution defined by the pilot signal modulation, e.g., a binomial distribution for binary phase shift keying modulation. Interference arising from such sources is relatively "benign" as compared to Gaussian interference and thus should be suppressed or otherwise discounted in signal quality calculations. Suppression may be based on subtracting benign impairment correlation estimates from total impairment correlation estimates, or on filtering the benign impairment in channel estimation.
摘要翻译：接收机电路可以从接收到的信号质量估计的计算中抑制“良性”损伤的影响，使得估计主要取决于非良性损伤的影响。例如，接收的信号可能经受相同小区和其他小区干扰加噪声，其通常使用高斯分布来建模，并且还可能是由于某些形式的自干扰，例如由不完美产生的正交相位干扰用于产生用于接收信号的信道估计的导频样本的去旋转。这种干扰通常采用由导频信号调制定义的分布，例如二进制相移键控调制的二项分布。与高斯干扰相比，从这些源产生的干扰相对“良性”，因此在信号质量计算中应被抑制或以其他方式折扣。抑制可以基于从总损伤相关性估计中减去良性损伤相关估计，或者在过滤信道估计中的良性损伤。

摘要： Exemplary received signal processing may be based on maintaining a model of received signal impairment correlations, wherein each term. of the model is updated periodically or as needed based on measuring impairments for a received signal of interest. An exemplary model comprises an interference impairment term scaled by a first model fitting parameter, and a noise impairment term scaled by a second model fitting parameters. The model terms may be maintained based on current channel estimates and delay information and may be fitted to measured impairment by adapting the model fitting parameters.based on the measured impairment. The modeled received signal impairment correlations may be used to compute RAKE combining weights for received signal processing, or to compute Signal-to-Interference (SIR) estimates. Combined or separate models may be used for multiple received signals. As such, the exemplary modeling is extended to soft handoff, multiple antennas, and other diversity situations.

摘要： A method for estimating a plurality of delay values in a multi-path communication signal. Correlation values are generated that correspond to a plurality of delay values associated with the multi-path communication signal. A first power-delay profile (PDP) sequence is produced from the correlation values and is used to estimate a first delay value. A first reference PDP sequence is generated based on a predefined PDP sequence and the first PDP sequence. The first reference PDP sequence is removed from the first PDP sequence so as to remove at least a portion of the contributions to the first PDP sequence from the first delay value, and to provide a second PDP sequence. A second value is estimated based on the second PDP sequence.

摘要： Received signals are decoded based on a coupling between bits of the received signals introduced by the channel over which the signal is transmitted or by the transmitter which transmitted the signals. For example, in a higher-order modulation scheme, such as 8-PSK, individual bits grouped in a given symbol are generally coupled rather than fully independent. Accordingly, decoding information on a first one of the bits processed through a forward error correction decoder may be used to adjust the soft information from a demodulator for one or more of the other bits contained in the same symbol for use in processing those bits through the forward error correction decoder. Particularly where interleaving is utilized, a first bit may be processed through the decoder before the soft information on another of the bits is needed, thereby allowing an intermediate decision soft value for the first bit to be used in generating the input value to the decoder for the subsequent bit. Alternatively, a multi-pass process may be utilized which may allow all of the bits to be decoded utilizing soft information from the first decoding pass to affect the input to the decoder during the second pass for coupled bits such as those transmitted in a common symbol.
摘要翻译：接收信号基于由发送信号的信道所引入的接收信号的位之间的耦合或通过发送信号的发送器进行解码。例如，在诸如8-PSK的更高阶调制方案中，分组在给定符号中的各个比特通常是耦合的，而不是完全独立的。因此，可以使用通过前向纠错解码器处理的比特中的第一个比特的解码信息来从解调器调整包含在相同符号中的一个或多个其他比特的软信息，以用于通过前向纠错解码器。特别是在使用交织的情况下，可以在需要对另一位的软信息之前通过解码器处理第一位，从而允许将第一位的中间判定软值用于向译码器生成输入值随后的一点。或者，可以使用多遍处理，其可以利用来自第一解码通过的软信息来解码所有比特，以在第二遍期间影响到解码器的输入，用于耦合比特，例如以公共符号。

摘要： An adaptive radio receiver utilizes control functions derived from received signals in an interference-limited environment to decide whether to implement conventional single-user demodulation or joint demodulation. The decision to implement joint or conventional demodulation is based upon the values of estimates derived for Doppler spread, carrier-to-interference plus noise, dispersiveness and the likelihood of the presence of a dominant interferer.

摘要： The computation of code-specific channel matrices for an Assisted Maximum Likelihood Detection (AMLD) receiver comprises separately computing high rate matrices that change each symbol period, and a low rate matrix that is substantially constant over a plurality of symbol periods. The high and low rate matrices are combined to generate a code-specific channel matrix for each receiver stage. The high rate matrices include scrambling and spreading code information, and the low rate matrices include information on the net channel response and combining weights. The low rate matrices are efficiently computed by a linear convolution in the frequency domain of the net channel response and combining weights (with zero padding to avoid circular convolution), then transforming the convolution to the time domain and extracting matrix elements. Where the combining weights are constant across stages, a common code-specific channel matrix may be computed and used in multiple AMLD receiver stages.

Balance is maintained by attenuating the influence of extrinsic information fed back from the decoder to the demodulator to prevent strong decisions by the decoder from overwhelming the demodulator.
