Abstract: the pseudorandom spreading sequence in the forward transmission in the IS-95 system is assigned only to individual base stations. To separate users, the system assigns orthogonal (Hadamard) sequences to each of them. In this paper, a different scheme for the forward transmission is considered. In this scheme pseudorandom sequences are used, instead of employing orthogonal spreading sequence for individual users. The effect of fade amplitudes, phase shifts, time-mismatching and AWGN on the detection process of Gold Sequence Spread Spectrum Signal (DSSSS) is considered.
Keywords: Gold sequence, Rake receiver, Time-mismatching, QPSK-DS SS receiver.
