摘要： The present invention provides a multi-branch equalizer processing module operable to cancel interference associated with received radio frequency (RF) burst(s). This multi-branch equalizer processing module includes both a first equalizer processing branch and a second equalizer processing branch. The first equalizer processing branch is operable to be trained based upon known training sequences and equalize the received RF burst. This results in soft samples or decisions which in turn may be converted to data bits. The soft samples are processed with a de-interleaver and channel decoder, where the combination is operable to produce a decoded frame of data bits from the soft samples. A re-encoder may re-encode the decoded frame to produce re-encoded or at least partially re-encoded data bits. An interleaver then processes the at least partially re-encoded data bits to produce and at least partially re-encoded burst. The second equalizer processing branch uses the at least partially re-encoded data bits to train linear equalizer(s) within-the second equalizer processing branch. A buffer may initially store the received RF burst(s), which are retrieved and equalized by the second equalizer processing branch once the linear equalizer(s) are trained. This results in alternate soft samples or decisions which in turn may be converted to alternate data bits. The alternate soft samples are processed with the de-interleaver and channel decoder, where the combination is operable to produce an alternate decoded frame of data bits from the alternate soft samples. This allows interfering signals to be cancelled and more accurate processing of the received RF bursts to occur.

摘要： The present invention provides a processing module operable to produce an improved channel impulse response. This process involves initially estimating the channel impulse response. This result is based on and combined with a known sequences such as that provided by training sequences of the midamble within RF bursts. From this combination, it is possible to produce an estimated signal from a convolution of the channel impulse response and midamble. The estimated signal may be cancelled or subtracted from the received signal to produce a clearer image of the disturber signal. A blind data recovery performed upon the disturber signal. The recovered disturber data may be used as a reference for disturber channel estimation in order to produce a disturber channel impulse response. With the estimated disturber channel impulse response and the recovered disturber data, an estimated disturber signal may be reconstructed and subtracted from the received signal. This allows the cancellation of the estimated disturber signal. Without a clear or dominant disturber signal, a better representation of the main channel impulse response may be produced. This results in more accurate processing of the received RF bursts and improved receiver performance.

摘要： An HSDPA rake receiver has a plurality of rake fingers. Different channels may experience different spreading factors. The channel estimate (CE) and the CE delay may be affected and depend on the spreading factor. The CE delay is related to the individual rake finger output buffer size. According to the structure of the present invention, an adaptive channel estimate delay that depends on the spreading factor may result in improved performance.

摘要： This invention provides channel dispersion estimation algorithm(s). This channel dispersion estimation algorithm(s) may be implemented within a channel length estimation module of a single-branch or multi-branch equalizer processing module that enables interference cancellation when the channel length or channel delay spread associated with received radio frequency (RF) bursts compares unfavorably to predetermined thresholds. The channel dispersion estimation algorithm identifies when the radio frequency (RF) bursts have a channel length or channel delay spread that can affect receiver performance. The channel length estimation module may disable interference cancellation in response to such a channel length or channel delay spread. Additionally, the channel length estimation module may adjust the number of equalizer states for the single-branch or first branch of a multi-branch equalizer based the channel length or channel delay spread. The multi-branch equalizer improves the signal-to-noise ratio by improving the equalization by selectively disabling interference cancellation and adjusting the number of equalizer states for the single-branch or first branch equalizer.

摘要： This invention provides colored noise detection algorithm(s). This colored noise detection algorithm(s) may be implemented with a multi-branch equalizer processing module that enables interference cancellation when colored noise is associated with received radio frequency (RF) bursts. The noise discriminator identifies when the radio frequency (RF) bursts have white noise or colored noise associated with them. Alternatively the noise discriminator may be able to determine and enable interference cancellation in response to an interference-limited received RF burst as opposed to a noise-limited received RF burst. The multi-branch equalizer improves the signal-to-noise ratio by improving the equalization with a second branch operable to be trained based upon known training sequences and at least partially re-encoded data bits.

摘要： A Space Time Transmit Diversity (STTD) Decoder includes a physical channel despreader, a delay buffer, an upper processing branch, a lower processing branch and a combiner. The upper processing branch is operable to apply a conjugate of a first channel estimate to the delay buffer symbol output and produce non STTD encoded symbols. The lower processing branch is operable to read delayed delay buffer symbol outputs and apply a conjugate of a second channel estimate when active in the STTD mode. The lower processing branch then may apply an STTD decoder scheme to the delay buffer symbol output to produce non STTD encoded symbols. The combiner then combines the non STTD encoded symbols of the upper processing branch and non STTD encoded symbols of the lower processing branch to produce a single set of non STTD encoded symbols.

摘要： Adaptive interference cancellation algorithm using speech mode dependent thresholds. A method of processing radio frequency (RF) bursts dependent on a speech mode associated with data contained within the RF burst is presented. Different voice modes, full rate, half rate, and adaptive multi-channel rates each may require different signal to noise ratio (SNR) conditions in order to be successfully processed. To improve the equalization, the SNR associated with the burst is estimated. Based on the SNR or other related conditions, a decision can be made as to whether or not an interference cancellation burst process should be implemented. For example, any one or more of SNR of the signal, a measure of colored noise within the signal, an indication whether the signal being noise limited or interference limited, and a channel profile of the signal may indicate the presence of interference requiring the cancellation of such interference.
