Exploiting channel symmetry in two-way channels

Wireless communication is frequently employed for the bi-directional exchange of information between devices with disparate capabilities. Mobile devices such as cellular phones and laptops are subject to stringent size weight and power constraints relative to the base stations or access points they communicate with. Asymmetry of constraints results in asymmetry of the cost of computation. This disparity in cost motivates efforts to shift signal processing such as channel estimation and equalization from cost sensitive devices to those with more relaxed constraints. In this work we develop a two-way training channel estimation and precoding scheme that shifts all the computation involved in dealing with multiplicative channel gain as well as frequency selective channels to the base station. This work demonstrates the first tractable implementation of a precoding based transceiver scheme of this class on the Rice University Wireless Open Access Research Platform (WARP).
