Abstract  Abstract

A system and method for processing information signal communication using spread spectrum communication technology. a plurality of PN sequence between the user providing orthogonal so as to reduce mutual interference between and allowing higher capacity and better link performance. under the condition of orthogonal code each point is zero on a predetermined time interval the result without the interference between the orthogonal codes provided by the code time frames are time calibration in one typical embodiment signals between cell site (12 14) and the mobile unit (16 18) communicate using a direct sequence spread spectrum communications signal.
