    “Worst experience ever . Don't hire him otherwise you will suffer. Even Don't bother to reply. Don't Care about Your deadline even after giving extra time. After accepting project, he will start find some cheaper freelancer and ask them to work. I can't explain how much i have suffered because of him. Don't trust at him.. Alaass..........!”

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.
