Song, L-Y. and Burr, A.G. (2007) Differential quasi-orthogonal space-time block codes. IEEE Transactions on Wireless Communications, 6 (1). pp. 64-68. ISSN 1536-1276
In this letter, we propose a simple differential spacetime block code with a quasi-orthogonal structure. A simple and general encoding procedure is presented, which differentially encodes the signal transmission matrix as a whole at the transmitter end. A novel power estimator is derived at the receiver to allow for the non-constant amplitude of the received signals. Simulation results show that our scheme has performance equal to the best full rate quasi-orthogonal schemes previously described, along with a simpler decoder.
