ABSTRACT:
The invention relates to zero-overhead, sequence reversible, and pattern independent orthogonal multiplexing to achieve high bit densities in direct sequence spread spectrum communication systems. A set of orthogonal spreading codes is selected. The orthogonal spreading codes are partitioned into partitioned sets. The partitioned sets are further expanded to include complement codes of the orthogonal spreading codes. The orthogonal spreading codes and the complement codes are mapped into a code index to create a spreading code set. A window of contiguous input data is partitioned into equal-size subsets, which are then mapped to a data index, to create a data set. The data set is mapped to the spreading code set to create a multiplex of spreading codes, and the multiplex of spreading codes are then summed to form a code multiplex. The code multiplex can then be sent in one transmit opportunity.
