Abstract

Proposed is a simplified weighted energy detector (WED) receiver structure for ultra-wideband impulse radio (UWB-IR) systems. The performance improvement of the WED comes with the cost of increased hardware complexity when performing linear combination over the fractional energies. In this proposed scheme, multiplication for the combination process is replaced with a register-shifting operation based on simplified weighting coefficients. Simulations show that the proposed WED structure achieves the same BER performance as a multiplier-using WED structure with much lower hardware complexity.
