Abstract :
The work establishes fundamental limits between rate, reliability and computational complexity, for the general setting of outage-limited MIMO communications. In the high-SNR regime, the limits are optimized over all encoders, all decoders, and all complexity regulating policies. The work then proceeds to explicitly identify encoder-decoder designs and policies, that meet this optimal tradeoff. In practice, the limits aim to meaningfully quantify different pertinent and interrelated measures, such as the optimal rate-reliability capabilities per unit complexity and power, the optimal diversity gains per complexity costs, or the optimal goodput per flop. Finally the tradeoff´s simple nature, renders it useful for insightful comparison of the rate-reliability-complexity capabilities for different encoders-decoders.
