Abstract

This paper investigates the problem of channel estimation and decoding of orthogonal space time block codes (OSTBCs) in a two-way amplify-and-forward (AF) multiple-input multiple-output (MIMO) relay network. We propose a joint decoder for a pilot symbol-aided two-way AF based MIMO cooperative system. The proposed decoder jointly processes the received OSTBC data and pilot matrix by using vector derivative over the two-way MIMO relay channel. We derive a closed-form expression in Rayleigh fading for the moment generating function of the received signal-to-noise ratio at both cooperating users for the proposed decoder; and then investigate the system performance based on analytical expressions for the symbol error rate, diversity order, and array gain.
