Algorithm of election of sequences of scattering of systems [cdma] for canals with selective fade-out in f

NOVELTY – A software allows preferential selection of sequences with the objective of minimizing errors in bit measurement for channels with selective fade in frequency. The selection depends on the diversity, scattering factor and signal to noise ratio per bit, and is based on the cross and auto correlations of the spreading sequences. USE – For CDMA systems. ADVANTAGE – Combats interference in channels with selective fade in frequency in multi-user CDMA environment.
