The Rake receiver has become very popular in wireless communication in recent years, but it has several drawbacks, including complexity, high noise, poor performance, and a slow transmission rate. As a result, a system with high performance, low complexity, low noise, and high efficiency is required. In this paper, a proposed adaptive transmitted reference receiver with dual-tree complex wavelet transform (DTCWT) was produced and analyzed by complex discrete wavelet transform (DWT). This proposed receiver achieves high performance, low complexity, higher transmission rate, and lower noise than previous rake receivers or wavelet transform systems. High frequencies that caused noise in the system were cut off using DWT. To remove these frequencies, DTC-DWT uses two types of FIR filters. To get a better result, use three levels in this system. A maximal ratio combiner (MRC) is used to capture most of the multipath components, and an adaptive filter of recursive least squares (RLS) is used to update MRC input. High gain UWB antenna was applied as single-in multi-out (SIMO) and multi-in multi-out (MIMO) to give a more powerful link for data to maximize channel capacity. The simulation results show that when dual-tree complex filters of three levels of noise reduction are used, the effect is to remove high frequencies that cause noise in the TR UWB received signal. The bit error probability is reduced according to the peak-average-power ratio (PAPR) compared with the conventional transmitted reference (TR) receiver.
