Abstract  Abstract

A system and process for communicating information signals using spread spectrum communication techniques is described. PN sequences are constructed that establish orthogonality between users in order to reduce mutual interference, allowing for higher capacity and better link performance. with orthogonal pn codes, the cross correlation is zero over a predetermined time interval, resulting in no interference between orthogonal codes, provided only that the time frames of the codes are aligned in time with each other. In one exemplified embodiment, the signals are communicated between a cell site and the mobile units by direct sequence propagation aspect communication signals. In the cell / mobile link, the link, pilot, synchronization, paging and voice channels are defined. Information communicated via cell / mobile link channels is generally encoded, interleaved, modulated by biphasic deviation key (bpsk) with orthogonal coverage of each bpsk symbol along with quadriphase deviation key (qpsk) coverage of the covered symbols . In the mobile link / cell, the link, access and voice channels are defined. Information communicated through the mobile link / cell channels is generally encoded, interleaved, and orthogonally signaled along with qpsk propagation.
