Title
Real-Time Implementation of 4x4 MIMO-OFDM System for 3GPP-LTE Based on a Programmable Processor
Abstract
MIMO-OFDM is currently being considered as a promising technology for future wideband wireless systems. Meanwhile, the detection of MIMO-OFDM system forms one of the most intensive tasks in baseband signal processing. There have been a great number of algorithms proposed for MIMO-OFDM detection. This paper investigates the real-time implementation of MIMO OFDM systems using programmable multi-SIMD (single instruction multiple data) processor targeting for software defined radio. We analyze the computational characteristic and cost of major algorithms of LPF, symbol synchronization, OFDM modulation, channel estimation and MIMO detection of a 4x4 MIMO-OFDM system based on 3GPP-LTE R-12 standard. The evaluation and implementation results show that our SDR architecture supports 300Mbps LTE system with 20MHz bandwidth. Finally, we discuss the architecture perspective of our SDR processor for future wireless communication standards with higher throughput.
