摘要
Relying on a layered algebraic design, we derive a new space-time-doppler (STD) code for multiple input multiple output (MIMO) time-selective fading channels. The proposed STD code achieves rate N-t and enables full-diversity NtNrNb(Q+1), i.e., the product of the number of transmit antennas Nt, receive antennas N-t coding blocks N-b and channel complex exponential bases (Q + 1). Simulation results show that the proposed STD codes achieve higher diversity gain in time-selective channels than some existing STD codes.
