In this paper, we analyze a full rate cooperative communication system using amplify-and-forward (AF) two-path relaying scheme with inter-relay interference cancellation at the relay. By treating AF two-path relaying as an equivalent MIMO system, we derive the pairwise error probability (PEP) of this system. Given one source node, two half duplex relay nodes, and one destination node, all equipped...
In this paper, we first propose a new class of full rate full diversity quasi-orthogonal space time block code (QO-STBC), namely QO-STBC with blind preceding (BP-QO-STBC). Based on this code, an open-loop MIMO multi-user downlink transmission scheme is derived. Presuming M blocks of BP-QO- STBC are transmitted from the access point simultaneously, thus achieving a multiplexing gain of M, we show that...
As the wireless channel is constantly changing, MIMO-OFDM eigenmode transmission is extremely vulnerable to the presence of feedback delay which is unavoidable in a practical system. Under such imperfect conditions, the inter-eigenmode interference can be removed through the use of the MMSE interference canceller. However, to the best of our knowledge, the performance of MIMO-OFDM eigenmode with MMSE...
