Numerically Optimized Uniformly Most Powerful Alphabets for Hierarchical-Decode-and-Forward Two-Way Relaying
Original language description
We address an issue of parametric performance of Hierarchical-Decode-and-Forward (HDF) strategy in wireless 2-way relay channel. Promising HDF, representing the concept of wireless network coding, performs well with pre-coding strategy which requires Channel State Information (CSI) at the transceiver side. Assuming a practical case when CSI is available only at the receiver side, the parametrization causes significant performance degradation for some modulation alphabets. The alphabets robust to the parametrization (denoted Uniformly Most Powerful (UMP)) have already been proposed restricting on non-linear multi-dimensional frequency modulations. In this work, we focus on general design of unrestricted UMP alphabets. We formulate an optimization problem which is solved by standard non-linear convex constrained optimization algorithms, particularly by Nelder-Mead global optimization search which is further refined by local interior-points method.
