Abstract

Code-multiplexed communication systems (100), apparatus, and methods include coders (Fig.1) that encode and decode data streams with synchronous, substantially orthogonal codes. Code-multiplexed communications systems (100) encode data signals with such codes to control levels of decoding artifacts such as cross-talk at times or time intervals in which data is recovered. Some systems are based on synchronous, orthogonal codes that are obtained from complex orthogonal vectors. In an example, a three-level temporal-phase code that includes nine code chips is used to encodes and decodes data signals is a seven-channel communication system.
