Indoor Channel Prediction Using an Efficient Sum of Sinusoids Linear Prediction Scheme

In this paper we present a method for predicting a wireless channel using an efficient sum of sinusiods (SOS) method. Our method models a channel as the sum of a discrete number of rays, and extrapolates these rays forward along a trajectory when given accurate measurements of the component rays at distinct spatial points. In simulations, we have been able to eliminate the need for regular pilot signals in an OFDM system over a distance of 10 cm, increasing system data throughput by 17% in the case of a moving receiver.
