Abstract

Due to multipath fading and inter-symbol interference, the high speed transmitted data extends to several symbol periods. Signals which travel through several paths get reflected by different objects and signals taking less direct path arrive at receiver later and are often attenuated. Traditional systems employ some improvement techniques to deal with multipath signals; one technique is to use multiple antennas to capture the strongest signal at each moment of time, another technique adds delays to back align the signals. This paper presents the use of channel state information for estimating the channel impulse response and its use in channel equalization on the transmitter side.
