Low Computation Complexity Two-Stage Feedforward Carrier Recovery Algorithm for M-QAM
Low Computation Complexity Two-Stage FeedforwardCarrier Recovery Algorithm M-QAM
2015/5/20
We propose a modified two-stage feedforward carrier recovery algorithm for M-QAM formats that achieves a 3x reduction in computation complexity compared to a single-stage algorithm. When combining wit...
Digital Clock Recovery Algorithm for Optical Coherent Receivers Operating Independent of Laser Frequency Offset
Digital Clock Recovery Algorithm Optical Coherent Receivers Laser Frequency Offset
2015/7/30
We propose a digital clock recovery algorithm and demonstrate its tolerance to at least 5GHz laser frequency mismatch in a 43Gb/s DP-RZ-QPSK receiver after 1200km transmission.
