Abstract  Abstract

SYSTEMS AND METHODS FOR USING CODE SPACE IN SPECTRAL SPREADING COMMUNICATIONS NETWORK. Systems and methods for improving the performance of forward sequence spread spectrum communication systems are described. In one embodiment, a system comprises at least one communication channel using two different orthogonal spreading codes and corresponding portions of the available orthogonal code space. Portions of the data processed by the communication channel are demultiplexed (471) to different currents and covered (472, 473) with correspondingly different orthogonal spreading codes. The currents covered by the different orthogonal codes are then combined (475) and transmitted over the same communication channel. One embodiment uses at least two different Walsh codes of different lengths (+ - and + + - -) to make use of the three quarters of Walsh space not used by legacy low rate channels.
