Performance of MIMO-UWB for LOS and N-LOS Propagation

UWB transmits low power capable of working on the low signal to noise ratios. It acts as a jamming resistance whereas its performance is very high in multipath channels. It has a large channel capacity and simple transceiver architecture. Its performance is high even in noisy environments and possesses the least probability of intercepting and detecting capability. UWB is favored for use in driven battery devices. In this work, we have focused to simulate and evaluate the performance of Non-line of sight (N-LOS) BER (0–4 m) multiple input and multiple outputs—UWB for line of sight (LOS) and N-LOS conditions using Quadrature Phase shift Keying (QPSK) transmission scheme. The parameters such as error vector magnitude (EVM), bit error rate (BER), signal to noise ratio (SNR), constellation diagram, the spectrum of transmitting and receive signal are discussed and analyzed.
