摘要： Space-time block codes (STBCs) is a known approach for using multiple transmit antennas to provide higher data rates and better reliability by exploiting spatial diversity. Existing STBCs use independent two-dimensional constellations. Methods and systems for using multidimensional constellations to improve the performance of orthogonal STBCs are disclosed. Methods for finding optimized multidimensional constellations for orthogonal STBCs are also disclosed.

摘要： According to embodiments, there is provided a method apparatus for determining an encoding scheme for transmission of encoded data across a communications channel. The method includes determining the encoding scheme at a design Signal-to-Noise Ratio and evaluating a Frame Error Rate of the encoding scheme. If the FER is not within a target range, the method further includes modifying the encoding scheme until the evaluated FER is within the target range. There is further provided a method and apparatus for mapping bit labels to a plurality of symbols in a constellation, wherein the constellation are organisable into a plurality of sets and each bit label includes a plurality of bit positions. The method includes determining a distance metric between sets and merging pairs of sets according to the distance metric. The method further includes assigning a value to a bit position for bit labels of symbols in the merged set.
