Detection of 56GBaud PDM-QPSK generated by commercial CMOS DAC with 11GHz analog bandwidth

We proposed optimal design of the post filter taps, for post filter + sequence detector receiver. The design is verified by detecting 56GBaud PDM-QPSK generated by commercial CMOS DACs with 11GHz analog bandwidth. Only 2.6dB@1e-2 penalty is observed.
