Abstract: A method of operation of a wireless communication system includes: filtering a composite input from a radio frequency signal; developing a raw digital stream by applying an analog correction to the composite input; sampling an extracted signal, from the raw digital stream, by a primary analog-to-digital converter; and monitoring, by a correction control block, the extracted signal including adjusting the analog correction by a digital control from the correction control block.

Abstract: A method of operation of a wireless communication system includes: tuning a receiver front end for receiving a radio-frequency signal; correcting, with an in-phase/quadrature (I/Q) compensation module, an I/Q imbalance from the receiver front end including estimating by a linear minimum mean-square error (LMMSE) module; and processing by a base band receiver for digitizing an output of the I/Q compensation module for generating a receiver data.

Abstract: A method of operation of a communication system includes: generating a filter impulse response and a filter time-domain data with a shortening filter; generating a filter frequency response based on the filter impulse response with a filter frequency response calculator; generating a filter frequency-domain data based on the filter time-domain data with a first process unit; and generating a raw channel impulse response with a filter frequency removal unit for removing the filter frequency response from the filter frequency-domain data.

Abstract: A multi-carrier receiver capable of receiving one or multiple frequency channels simultaneously is described. In one design, the multi-carrier receiver includes a single radio frequency (RF) receive chain, an analog-to-digital converter (ADC), and at least one processor. The RF receive chain processes a received RF signal and provides an analog baseband signal comprising multiple signals on multiple frequency channels. The ADC digitizes the analog baseband signal. The processor(s) digitally processes the samples from the ADC to obtain an input sample stream. This digital processing may include digital filtering, DC offset cancellation, I/Q mismatch compensation, coarse scaling, etc. The processor(s) digitally downconverts the input sample stream for each frequency channel to obtain a downconverted sample stream for that frequency channel. The processor(s) then digitally processes each downconverted sample stream to obtain a corresponding output sample stream.

Abstract: In a code division multiple access communication system (100), a method and accompanying apparatus provide for controlling gain of a forward supplemental channel (482) by determining gain level of a forward fundamental channel (481) associated with supplemental channel (482) for being targeted for a common mobile station, determining an adaptive margin (Ma) for fundamental channel (481) and determining a forward supplemental channel gain (Gsch) based on the gain of supplemental channel (482) and the Ma. The Gsch may be successively decreased for subsequent data frames targeted for the common mobile station on supplemental channel (482) by successively decreasing the Ma until receiving a supplemental channel frame erasure indicator from the common mobile station. The Gsch may be increased for a subsequent data frame targeted for the common mobile station on supplemental channel (482) by increasing the Ma after receiving the supplemental channel frame erasure indicator from the common mobile station.

Abstract: A method and apparatus for providing an improved soft handoff algorithm in a wireless communication system for third generation code division multiple access (“CDMA”) systems.

Abstract: Techniques are described whereby noise estimates from individual finger processors are compared using a noise estimator, and a finger merge condition declared on the basis of such comparison. In one embodiment, when noise estimates from two or more finger processors is identical or nearly identical, finger merge is presumed such that noise estimates from merged fingers are blocked from forming a combined noise estimate. Furthermore, in another scheme a correcting factor is introduced to account for the correlation between noise samples from merged fingers. In a further embodiment, a computationally effective procedure to perform comparisons between the noise estimates from individual fingers is implemented by sorting noise estimates according to respective magnitudes to create a sort list. In one implementation, only samples that are neighbors in the sorted list are then compared.
