Performance evaluation of mmWave single carrier systems with a novel NLOS channel model

Abstract

In this paper, we evaluate the performance of a low-complexity 60 GHz system in a realistic non-line-of sight indoor environment. We consider a single-carrier transmission system that does not employ equalization, but only uses forward error correction. The channel model was created from measurements in a conference room in which a non-line-of-sight environment is created through a human-sized blocking object, and in which beamforming is applied at the receiver to track and obtain reflected paths. We obtained the bit error rate performance using channel impulse responses obtained from measurements and from the resulting channel model. Our evaluation indicates that the system can achieve the target bit error rate. As a result, we not only verified the new channel model but also show that complex equalization methods are not necessary to achieve reliable communication in indoor 60 GHz scenarios.
