Abstract  Abstract

FIELD: communications engineering; data signal exchange with spectral extension of messages. SUBSTANCE: with orthogonal pseudorandom noise codes mutual correlation equals zero at predetermined time interval so that no interference exists between orthogonal codes on condition that time intervals of codes are aligned. Cellular assembly and mobile pieces of equipment use direct sequential extended-spectrum communication signals for exchanging messages. Monitoring synchronizing page and voice channels are discriminated in cell-to-mobile-equipment communication line. Data transmitted over this communication line is coded interlaced modulated by two-phase key shift with orthogonal coverage of each character modulated by two-phase key shift and with extension of covered characters by quadrature-phase key shift. Access channel and voice channel are separated in mobile-equipment-to-cell line. Data transmitted over channels of mobile-equipment-to-cell line is coded interlaced and orthogonally indicated along with extension by quadrature-phase key shift. EFFECT: reduced mutual interference increased carrying capacity and improved quality of communication line. 61 cl 15 dwg
