The generator produces up to 16 code channels and provides independent control of the gain and Walsh code spreading for each channel.
Well-known families of linear spreading sequences, such as m-sequences, Kasami, Gold, and Walsh codes, traditionally employed as channelization codes, exhibit non-zero and sometime non negligible auto- and cross-correlation out-of-phase values, which limit the achievable performance, in asynchronous or in quasi-synchronous scenarios [11].
This relationship holds for both the Hadamard numbering of the Walsh codes in IS-95 and CDMA2000 as well as the bit-reversed Hadamard code numbering used in wideband CDMA (W-CDMA).
