Abstract  Abstract

system and method for improving direct sequence spread spectrum communication system. In one embodiment a system comprises: at least one communication channel the channel using the corresponding part of two different orthogonal spreading codes and the available orthogonal code space. the data processed by the communication channel portion is demultiplexed (471) into different streams and the corresponding different orthogonal code covers (472 473). Then the flow is combined with different orthogonal code covers (475) and via the same communication channel. In one embodiment in order to use three quarters of the Walsh space is not traditional channel using at least two different Walsh codes (+ - and + + --).
