METHOD AND SYSTEM FOR ADAPTING AN EFFECTIVE SPREADING SEQUENCE IN A COMMUNICATION SYSTEM USING DIRECT SEQUENCE SPREADING

摘要

using the present invention is a direct -sequence spread- adapting an effective spreading sequence in a wired or wireless communication system relates to a method and system . Station of the communication system is for example an impulse response , a step response , or to determine the status of the communication channels represented by any other characteristic known to those skilled in the art . The station determines the channel state by receiving a feedback signal containing information that is measured or stations of the received signal determining the plurality of linearly related phases . The station subsequently determines the phase according to a plurality of linearly according to the state of the communication channel , is applied to at least one sample of the effective spreading sequence at least one of the plurality of linearly related phases .
