A comparison of three diagonalizers, adaptive crosstalk cancellers, in dual-polarized M-QAM systems

Three different adaptive diagonalizers are compared on a probability of symbol error performance basis for dual-channel M-QAM systems. One diagonalizer (D3) greatly outperforms the other two, and any comparison of the performance of the diagonalizers to that of the minimum mean square error (MMSE) canceller should be based on D3. Receiver structures are also presented.<
