AbstractUsing a class of recently proposed linear scalable space-time codes we demonstrate the tradeoff between spatial multiplexing and transmit diversity for Rayleigh and Ricean flat fading. The codes are able to use jointly transmit diversity in combination with spatial multiplexing, and they achieve spatial and temporal diversity in Rayleigh and Rice fading environments. Frequency diversity of frequency selective channels can be utilized by combining the considered codes and OFDM. Simulation results for different scenarios show that a system consisting of the considered codes and decoder meets the requirements of future communication systems, e.g. it is possible to exploit high diversity factors and handle high rates with a reasonable and scalable complexity.
