PACKET DETECTION SCHEME USING CROSS CORRELATION AND INPUT SIGNAL POWER IN MB-OFDM UWB SYSTEM

摘要

PURPOSE: the detection method MB-OFDM UVWB systems of grouping, which provide, executes interblock interference function more effectively under various SNR multichannels fading channel environments, leads to the probability of false detection of data packet by reducing the factor, according to the input signal of amplitude. ;CONSTITUTION: packet detector (4) includes energy calculator (20), phase cross-correlator (30), power calculator (40), amplitude-normalized (50), correlator (60), energy value controller (70) and detector (80). Phase cross-correlator calculates the value between cross-correlation, according to the receiver of the method for MB-OFDM UWB signals and leading code value (10). The detector detects effective grouping. ;The 2011 of copyright KIPO submissions
