The problems of the orthogonal direct sequence spread spectrum signals choice for the signal processor on the SAW convolver basis with reference to the air-interface of the code-time division multiple access system (CTDMA) are considered. The locally-orthogonal signals with the use of Gold spreading sequences, compatible with the GMSK modulation system, referred to the GSM standard are investigated. The choice of the optimal demodulator scheme providing the integrated GSM/CTDMA air signal-to-interference ratio is established.
