Abstract

This paper presented signal detection algorithms for IEEE 802.11a orthogonal frequency division multiplexing (OFDM) systems. Signal detection is to detect the arrival of the OFDM packets. Due to the burst transmission characteristics, a simple and robust signal detection algorithm is required for practical hardware implementation. In this paper, we designed and compared three signal detection algorithms, which were based on the short training sequence transmitted in front of each OFDM packet. Computer simulations were conducted to evaluate the performance of these three signal detection algorithms.
