Abstract: A decoder (215) implemented in a receiver of a wireless communication system employs an improved method and apparatus for decoding an encoded signal. The receiver sums the energy values (156A, 156B, . . . 156N) from a plurality of fingers within to produce an aggregate energy value (166). From the aggregate energy value (166), a set of log-likelihood values (207) are generated with a non-linear function generator (205) before being deinterleaved by a deinterleaver (210). The deinterleaved values (213) are input to the decoder (215) which estimates the original signal (178) by incorporating path histories of bits in the estimation of subsequent, related bits. Use of the path histories of bits improves the estimates of the original signal (178), which translates into an increase in the sensitivity of the receiver.

Abstract: A method and apparatus is provided for creating a composite waveform. This composite waveform is created by coding a plurality of input digital information signals. Subsequently, the plurality of coded input digital information signals are communicated over a communication medium to a digital combiner. The digital combiner combines the plurality of coded input digital information signals. Finally, the digitally combined information signal is spectrally shaped to form a composite waveform. These composite waveform creation principals may be applied to digitally encoded voice subbands in a subband coding system as well as channel information in a direct sequence code division multiple access (DS-CDMA) communication system transmitter.
