ISWCS 2017, 14th International Symposium on Wireless Communication Systems, 28-31 August 2017, Bologna, Italy
Although the base station processing and the majority of the protocols of the wireless systems are standardized by 3GPP, the receiver architecture and implementation remain
vendor-dependent. The receiver design should fulfill computational efficiency requirements, and be evaluated in practical simulators or emulators that are compliant with real-world wireless standards. In this paper, we provide a comparative study of two low complexity Maximum-Likelihood receivers with the Parallel Interference-Aware (PIA) detection and with the Successive Interference Canceling (SIC) detection. Given 5MHz of LTE bandwidth, the SIC receiver achieves up to 4Mbit/s throughput gain in Rician fading and 1.8Mbit/s in Rayleigh fading compared to the PIA receiver. The quantification of computational effort demonstrates short signal processing time,
which makes our receivers suitable for real-time modems. Our empirical simulations deliver insights on the optimal SNR regimes and the modulation and coding schemes combinations for both codewords to maintain high level of throughput.
