Speech Title: Novel Symbol Detection Techniques in a Multi-Antenna 5G and Beyond Communications System

Speech Abstract: Significant performance gains are achievable in wireless communication systems using a Multi-Input Multi-Output (MIMO) communications system employing multiple antennas, being used in 5G and beyond Mobile Cellular Systems. This architecture is suitable for higher data rate multimedia reliable communications. One of the challenges in building a MIMO and Massive MIMO communications system is the tremendous processing power required at the receiver side. MIMO Symbol detection involves detecting symbol from a complex signal at the receiver and this symbol detection problem becomes even more complex in a massive MIMO system. The existing MIMO detection techniques can be broadly divided into linear, non-linear and exact detection methods. Linear methods like Zero-Forcing offer low complexity with degraded Bit Error Rate (BER) performance as compared to non-linear methods like VBLAST. Non-linear detectors are computational not very expansive with acceptable performance. Exact solutions like Sphere Decoder provide optimal performance however do suffer from exponential complexity under certain conditions. Computational Swarm Intelligence based Meta-heuristics can be applied for Symbol detection in a MIMO and Massive MIMO system with acceptable performance as compared to classical techniques. This approach is particularly attractive as Swarm Intelligence (SI) is well suited for physically realizable, real-time applications, where low complexity and fast convergence is of absolute importance. Application of Particle Swarm Optimization (PSO) and Ant Colony Optimization (ACO) algorithms has shown promise in this regards. While an optimal Maximum Likelihood (ML) detection using an exhaustive search method is prohibitively complex, we present that the Swarm Intelligence optimized MIMO detection algorithms gives near-optimal Bit Error Rate (BER) performance in fewer iterations, thereby reducing the ML computational complexity significantly. Therefore, novel non-conventional MIMO detection approaches based on Swarm-Intelligence techniques provides an alternative symbol detection technique that possess significant application in 5G and beyond Cellular Systems. The results of above work have already been published in several renowned journals and conference proceedings.
