This paper presents a MIMO two-way relaying
scheme where the transceiver filter at the Relay Station (RS)
processes the data using Recursive Least Square (RLS)
technique based on Inverse QR (IQR) algorithm. The relaying
technique used is Amplify and Forward scheme (AF). The
channel is assumed to be frequency selective and the Channel
State Information (CSI) is available only at the RS. So the
transmit and receive processing are both done at the RS.
Orthogonal Frequency Division Multiplexing (OFDM) is used
so as to combat the Inter-Symbol Interference (ISI) occurring
due to the frequency selectivity of the channel. The
performance of the IQR-RLS algorithm is verified by
comparing its Mean-Square error performance (MSE) with
that of a transceiver filter based on Normalized Least Mean
Square (NLMS) algorithm.
