IS-95A Base Station Receiver Library

The Base Station Receiver Library provides the blocks required to perform the CDMA system base station or reverse link receiver functions.

Function 
Block(s) 
Combining of the different rake fingers and the subsequent Walsh demodulation of the combined signal, while also accounting for the randomized transmit bursts
IS-95A Rev Ch Detector (includes IS-95A Rev Ch Rake Finger and IS-95A Rev Ch Walsh Demodulator)
IS-95A Rev Ch Walsh Demodulator
Noncoherent rake correlator that despreads the signal by correlating with the short and long PN codes and the Walsh sequences
IS-95A Rev Ch Rake Finger (includes IS-95A Rev Ch Short Code Despreader and IS-95A Rev Ch Walsh Correlator)
IS-95A Rev Ch Short Code Despreader
Correlation of the received and despread sequences with the Walsh sequences
IS-95A Rev Ch Walsh Correlator
Channel decoding of the raw data to recover the speech or user data
IS-95A Rev Ch Viterbi Decoder
