Abstract

This paper presents a new method for channel impulse response measurement with a suitably designed binary sounding sequence. This method minimizes the system overhead and results in ideal channel estimation using three correlators instead of one. This system complexity can be easily overcome by the present technologies. The class of sounding sequences used in this method is the training sequence for channel impulse response measurement with the zero values of the autocorrelation function at all shifts except zero and middle shifts in European digital cellular mobile telephone systems based on the global system for mobile communication (GSM). Computer searches are carried out to find the suitable sounding sequences
