A Parallel Detection and Decoding Technique for MIMO Communication Systems
Two of important requirements of fifth generation new radio (5G- NR) access networks are very high capacity
and ultra-reliability. In this paper, we proposed a V-BLAST 𝑵𝒕 𝑵𝒓 MIMO system that is analyzed and improved, and
expected to achieve both very high throughput and ultra-high reliability simultaneously. A new detection technique called
parallel detection and decoding algorithm is developed and compared with existing linear detection algorithms. It was seen
that the proposed technique increases the speed of signal transmission, provides high throughput and prevents error
propagation, which may be present in serial decoding techniques. The new algorithm reduces the bit error probability and
increases the capacity simultaneously without using STC. However, it was seen that the BER of MIMO systems using the
proposed algorithm is higher than a similar systems using standard STC technique, and it is lower than system using
MGSTCs technique. Simulation results show the advantages of the proposed technique.
