1 real spreading sequences is a function of the squared cosine of path phase offsets. By this 2 reason, the employment of the orthogonal unified complex Hadamard transform spreading 3 sequences in the DS-CDMA downlink wireless communication system using the GR 4 provides the better BER performance with respect to the DS-CDMA downlink wireless 5 communication system using the GR with the WH real spreading sequences, especially, at 6 high SNRs. Evaluation of the BER performance demonstrating the benefits of employment 7 of the unified complex Hadamard transform spreading sequences and MMRC weights in 8 the GR employed by the DS-CDMA downlink wireless communication system has been 9 carried out over simulation. Comparative analysis of employment of the GR and Rake 10 receiver in the DS-CDMA downlink wireless communication system with the orthogonal 11 unified complex Hadamard transform spreading sequences and the WH real spreading 12 sequences has been performed over simulation. Comparison showed a great superiority in
