Blind Adaptive Transmitted Reference Receiver Based on Indoor Wireless Propagation

In wireless ultra-wideband (UWB) communication systems, the high data rate propagation is exposed to multiple-users interference (MUI), inter-symbol interference (ISI), and multiple-access interference (MAI), which are influencing the enhanced and performance of the wireless reception systems. In this work, the blind adaptive filtering of mean square error (MSE) adaptive filter in the transmitted reference (TR) receiver was presented with the spread signal by time hopping spread spectrum (TH-SS) technique. The structure of adaptive TR receiver was presented by adjusting the adaptive filter tap weights using constant modulus algorithm (CMA), Godard algorithm (GA), Sato algorithm (SA), and affine projection CM algorithm (APA) to mitigate the multiple interference singles by supporting the weak required signals. The simulation results of symbol error rate (SER) versus signal-to-noise ratio (SNR) are illustrated to show the system performance of the proposed TR receiver.
