Abstract:
1. In a spread spectrum system of the type that processes a plurality of waveforms transmitted by respective users, the improvement comprising: two registers associated with l two further registers, each for storing mask sequences associated with the code sequences of a respective one of the l a first logic unit coupled to said registers for performing an arithmetical operation on said code sequences and mask sequences to generate, for mth transmitted symbol, (l, k) element of a matrix that represents correlations among the code sequences associated with the respective users, a second logic unit coupled to said first logic unit to generate a matrix that represents correlations among the waveforms transmitted by the users as a function of the matrix that represents correlations among the code sequences associated with respective users, and a third logic unit coupled to said second logic unit for computing detection statistics corresponding to symbols transmitted by the users.
