In the packet based systems for supporting burst data traffic networks, the fast synchronization is required in the short period of time upon receiving the data frame at the receiver. This important operation is generally carried out at the header part of the packet which is usually called the preamble. While detecting the existence of the valid signal frame through the carrier sensing it is also important to adjust the signal level at the input of the baseband blocks. This is generally called automatic gain control and it is essential to minimize the processing time for the gain decision for incoming received signals. In this paper, target level of the AGC is determined based on the bit-error-rate (BER) performance and SQNR for the varying power of the AGC input signal. The other parameters are optimized by utilizing statistics of the incoming signal including the degree of saturation as well as the incoming signal power. The proposed optimization method provides the improved convergence speed which in turn results in the reduced processing time.
