Quantitative Analysis of MIMO-OFDM System in CMOS Technology

Coupled with a robust and efficient OFDM air interface, MIMO technologies lead to a very compelling high speed data link solution for future wireless multimedia systems. This article presents MIMO-OFDM concept prototype of signal processing operations and simulate performance results. The prototype is based on the IEEE 802.11a/g standards at physical layer, supporting multiple antennas, adaptive modulation and coding, with peak rates up to 54 Mb/s. The proposed prototype architecture is modelled using VHDL-AMS-RTS, and synthesized using 0.35 mum CMOS standard cell library with a SYNOPSYStrade tool, as well as doing a timing simulation. It enables high throughput, high energy efficiency and small area, and can be readily sent for fabrication in a CMOS process
