IS-95A Mobile Station Transmitter Library
The Mobile Station Transmitter Library provides the blocks required to perform the CDMA system mobile station or reverse link transmitter functions. The functions and their corresponding blocks are shown below.
Function |
Block(s) |
Channel coding and interleaving of the information bits for error protection |
IS-95A Rev Ch Convolutional Encoder IS-95A Rev Ch Repeater/Derepeater IS-95A Rev Ch Interleaver/Deinterleaver |
Modulation of the signal to spread its spectrum |
IS-95A Rev Ch Walsh Modulation and Spreading (includes IS-95A Rev Ch Walsh Modulator and IS-95A Rev Ch Burst Randomizer) |
Walsh modulation, which involves the conversion of the channel symbol bits to one of several orthogonal Walsh codewords |
IS-95A Rev Ch Walsh Modulator |
Burst randomization, which consists of the gating of the transmitted signal using the long code |
IS-95A Rev Ch Burst Randomizer |
