A new space-time-doppler code for time-selective fading channels

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 N_tN_rN_b(Q +1), i.e., the product of the number of transmit antennas N_t, receive antennas N_r, 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.
