FPGA Implementation Platform for MIMO-OFDM Based on UART

Most hardware designers use Simulink as a design platform because it contains many components that have hardware equivalent. In addition to that, it supports Matlab Co-simulation and hardware synthesis. Simulink is seen as a good platform for low complexity systems that do not require trimming analysis during the verification phase.

Rapid prototyping of MIMO-OFDM based on parity bit selected and permutation spreading

In this paper, a novel transmission scheme is developed to effectively combine permutation spreading technique with MIMO-OFDM to obtain improved bit error rate performance in the presence of frequency selective fading channels with low system complexity.
