Programmable implementations of MIMO-OFDM detectors: Design, benchmarking and comparison

摘要

Programmable MIMO-OFDM detector design, benchmarking and comparison of implementations have been considered in this paper. We emphasize the significance of co-optimizing the algorithm, software and hardware together in order to reach demanding energy, latency and area restrictions introduced in current standards. We compare energy consumption of the detection algorithms based on the theoretical complexities in function of signal-to-noise ratio. Applying co-optimizing we show how a carefully designed programmable architecture can achieve the 3G long term evolution (LTE) detection rate requirements with a reasonable energy consumption.
