64 QAM signal constellation which is robust in the presence of phase noise and has decoding complexity |
摘要 |
A 64 QAM signal constellation reduces phase noise as compared with a rectangular constellation, but requires a fairly simple decoder. The constellation has decision regions which are approximately rectangular; allows for quadrant decoding; and has constellation points representable by a small number of bits.
