摘要： A method of adjusting a power control setpoint threshold (216) in a wireless communication system is provided. The method includes the steps of receiving at a receiver, a communication signal from a mobile communication unit to form a received communication signal, generating a first signal quality indicator (193) based on the received communication signal, generating a second signal quality indicator (194) based on the received communication signal, and generating an estimated signal-to-noise ratio (98). The method further includes setting a predetermined reference region (605) centered around a second signal quality indicator reference (206) where the second signal quality indicator reference (206) is related to the first signal quality indicator (193), and adjusting the power control setpoint threshold (216) based on a comparison between the second quality indicator (194) and the predetermined reference region (605).

摘要： Interleaving within a communication system occurs by finding a minimum value (m). A maximum-length sequence generator is initialized to 1 and a bit reverse sequence generator is initialized to 0. An n bit output is determined from the bit reverse sequence generator (101), and an m bit output is determined from the maximum length sequence generator (102). Finally, the n bit output is used as a most significant bit and m bit output is used as a least significant bit for an interleaver address (104).

摘要： A base station receiver assembly (400) for performing a signal search, which operates in a coherent code division multiple access (CDMA) wireless communication system conveying a mobile communication signal is disclosed. The assembly (400) includes a multipath signal searcher (200), a receiver (300), and an energy adjustment generator (490). The energy adjustment generator operates to combine an energy metric (241) from the multipath signal searcher (200) with a symbol match count (447) to yield a signal (448) for weighting inputs to a finger manager (260). The symbol match count (447) is based on a count, resulting from a comparison of a number of times an output from the multipath signal searcher (200) matched an output from the receiver (300). The symbol match count (447) is representative of a likelihood that a time offset selected by the finger manager (260) corresponds to a time offset of the mobile communication signal (107).

摘要： A method of determining an encoding rate associated with a received data frame in a communication system includes decoding (101) the received data frame at a first and second encoding rates to determine a first and second total metric, calculating (102) a discriminant function based on the first and second total metric, comparing (103) the discriminant function to a range of predetermined values having an upper predetermined range limit and a lower predetermined range limit, and selecting (104) one of the first and second rates as a determined encoding rate based on comparing (103) depending on whether the discriminant function is above the upper predetermined range limit or below the lower predetermined range limit.

摘要： A receiver (500) utilizes parameters generated by a Viterbi decoder (530) to determine one of a plurality of coding rates in which user information is transmitted. The receiver (500) combines the parameters in a predetermined manner, the result of which is a detection statistic (dij). By utilizing the detection statistic (dij), the coding rate at which user information is transmitted is accurately determined.
