This thesis describes new techniques of detection and fast start-up channel estimation for transmitting digital data over a fast 'frequency-selective' fading channel of the type encountered in fading mobile communications. The model of the channel involves a large number of reflected signals delayed in time by different amounts and reaching the receiver via different paths, each of which is represented by an independent Rayleigh fading channel. Such a model gives rise to frequency-selective fading and an appreciable degree of intersymbol interference. Base bend representation of the quadrature amplitude modulated data transmission system is first studied.
