摘要： A portable communication device including a power control system which estimates Eb/Nt by determining the variance of the noise components of PCBs that are received on the fundamental traffic channel. The power control system includes a demodulator for demodulating a BPSK modulated (or PAM) first signal from a base station, a noise variance calculation circuit that samples the perpendicular noise component of the demodulated signal to determine a noise variance, a power estimation circuit that measures the power of the demodulated signal and provides an estimate of the power of the first signal by eliminating the noise variance from the demodulated signal, and a comparator that compares the ratio of the power estimate and the noise variance to a threshold. The comparator output is a power up or power down signal to the base station.

摘要： Systems and methods for communicating source data between a source device and a listener device are disclosed. In an exemplary embodiment, source data is encoded by organizing at least a selected portion of source data into a data block having rows and columns. Encoded columns are formed by appending to each column error correction data derived from that column using a selected error correction code. Encoded rows are formed by appending to each row error correction data derived from that row using a selected error correct code. In an exemplary embodiment, encoded rows of source data (together with appended FEC data) and a first predetermined number of rows of FEC data are transmitted together, such that the first predetermined number of rows is less than all rows of error correction data. In an exemplary embodiment, source data is organized using interleaving.

摘要： An initialization method is performed to initialize the states for producing downlink scrambling code for a wideband code division multiple access (WCDMA) mobile device. The initialization method uses an auxiliary linear feedback shift register (x-LFSR) advance the x-initial state to a new initial state that corresponds to a selected downlink scrambling code. The new initial state allows the remaining masks used for generating the downlink scrambling code to be fixed. Memory required to produce the downlink scrambling codes is therefore reduced, as it is no longer dedicated to storing the sets of masks corresponding to each of the possible downlink scrambling codes.
摘要翻译：执行初始化方法以初始化用于宽带码分多址（WCDMA）移动设备的用于产生下行链路扰码的状态。初始化方法使用辅助线性反馈移位寄存器（x-LFSR）将x初始状态提前到对应于所选择的下行链路扰码的新初始状态。新的初始状态允许用于生成下行链路扰码的剩余掩码是固定的。所以产生下行扰频码所需的存储器因此被减少，因为它不再专门用于存储对应于每个可能的下行链路扰码的掩码组。

摘要： A fast, low-complexity detection scheme for determining the delays and gains of different propagation paths (i.e., multi-paths) of a received WCDMA signal. The method utilizes a continuous pilot channel that is scrambled by an known pseudo-random sequence. The received signal is provided to a multi-path searcher that passes the received signal through a matched filter with a specified number of taps. The matched filter correlates the received signal with the pilot channel. The multi-path gain and delay detection is then performed, and the delays and gains are reported for use in the WCDMA system.

摘要： Techniques for location-assisted wireless communication use real-time location(s) of wireless transceiver(s) together with stored location-indexed channel information to improve communication over a wireless channel between the transceiver(s). The stored channel information includes channel characteristics (e.g., average power, angle-of-arrival, and time delay of multipath components) that are substantially constant in time but vary gradually as a function of location. Current transceiver location(s) are obtained and used to retrieve stored channel characteristics corresponding to the location(s). The channel information may be used at either or both transceiver(s) to improve reception and/or transmission of signals propagating over the wireless channel. For example, reception may be improved by using path angle information to perform spatially structured reception, or using path delay information to perform temporally structured reception, e.g., to assign fingers to multipath components in a RAKE receiver and/or to track time delays of multipath components.
