报告内容
Modulation and code design for multiple antennas, namely space-time coding, has been studied extensively over the past decade. Some of the designs have been successfully used in current wireless communication systems. An important difference between single and multiple antenna modulations is the demodulation complexity. For a high bandwidth efficiency space-time modulation/coding, its maximum likelihood (ML) demodulation/decoding may be prohibitively high. Unfortunately, most of the existing space-time codes/modulations are designed based on the ML decoding and they perform well when ML decoding is used but may not perform well otherwise, which may be a problem in practical applications. In this talk, we first briefly review some of the well known space-time codes/modulations. We then propose space-time code/modulation designs based on low complexity receivers, such as linear receivers and partial interference cancellation (PIC) group decoding/demodulation.
