Abstract :
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 Nt and enables full-diversity NtNrNb(Q + 1), i.e., the product of the number of transmit antennas Nt, receive antennas Nr, coding blocks Nb 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.
