What: Space-time 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 is capable to offer powerful spatial diversity gain and/or multiplex capability without consuming precious bandwidth resources. Unfortunately, all currently available space-time coding schemes were proposed based mainly on bit-level block coding or trellis coding schemes, and their performances are extremely sensitive to multi-user interference and multipath interference. This talk presents a tutorial on chip-level space-time coding, which works based on three-dimensional spreading coding. Different from the traditional bit-level space-time coding, the chip-level space-time 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 space-time coding offers a unique paradigm, in which space-time 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.
