  • изображение Os A. Project for Ahmed M. $120.00 USD

    “The deadline for my project was very short. But Ahmed did everything possible in this short time frame and did an outstanding job. He explained everything whenever I got stuck or got confused of some part of work. So, I must say, he is a great communicator with complex things. I would definitely recommend him.”

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.
