Compress-and-forward relaying with polar codes for LTE-A system
Natarajan Madhusudhanan, L. Nithyanandan · 2014
Deploying compress-and-forward relay nodes is a promising and better solution for LTE-A networks to meet the capacity and coverage requirements of 4G and beyond systems. However, selecting a relay plays an important role in enhancing the benefits. In this paper, a compress-and-forward relay is proposed using polar codes which achieves better performance than turbo codes, but more importantly with less time complexity and reduced processing delay. Simulation results proved a major improvement of the system performance in terms of block error rate and processing delay.
