An Affine Projection Algorithm based transceiver filter for MIMO two-way relaying scheme

This paper presents a MIMO two-way relaying scheme where the transceiver filter at the Relay Station (RS) processes the data using a variant of the Affine Projection Algorithm (APA), known as Partial Rank Algorithm (PRA). The relaying technique used is Amplify and Forward scheme (AF). The modulation...

Description
Summary:This paper presents a MIMO two-way relaying scheme where the transceiver filter at the Relay Station (RS) processes the data using a variant of the Affine Projection Algorithm (APA), known as Partial Rank Algorithm (PRA). The relaying technique used is Amplify and Forward scheme (AF). The modulation technique used at the nodes S 1 and S 2 is Quadrature Phase Shift Keying (QPSK). The performance of PRA algorithm is verified by comparing its Mean-Square error performance (MSE) and Bit Error Rate (BER) with that of a transceiver filter based on Normalized Least Mean Square (NLMS) algorithm. The computational complexity of the algorithm is also tabulated.
