Abstract
In a robust system and method for detecting packets in SISO and MIMO broadband multicarrier transmission, a packet detector computes continuously the sum of the moduli of the power-normalized auto-correlations of a sequence of received signals (), tuned on the periodicity of the training symbols. When the power-normalized auto-correlation exceeds a first predetermined threshold (), then the maximum value of the sum of the moduli of all the cross-correlations between the received signals and the M aperiodic sequences is computed in a given time window (), sliding in time from −cto c. A packet is identified as received () when the maximum value of the sum of the moduli of the cross-correlations exceeds a second predetermined threshold ().
