ST coding plays a critical role in separation of signal transmissions via different transmitter and receiver pairs, and thus it lays a foundation for implementation of MIMO technology, which offers spatial diversity gain and/or multiplex capability without consuming precious bandwidth resources. Unfortunately, all current ST coding schemes were proposed based on bit-level block coding or trellis coding schemes, and their performances are sensitive to multi-user interference and multipath interference. This talk presents chip-level ST coding, which works based on three-dimensional spreading coding. Different from the traditional bit-level ST coding, the chip-level ST coding is robust due to its superior interference-resistant performance, and it is in particular suitable for its applications in futuristic wireless communications where both multi-user interference and multipath interference are present. In addition, the chip-level ST coding offers a unique paradigm, in which ST coding can be designed jointly with the signature codes in a code division multiple access system as an effort to optimize the system performance as a whole.
