K-Means Clustered Polyphase Filtering for Sample Rate Conversion in Coherent Polarization Multiplexing Fiber Optic Systems

摘要

A method for clustered polyphase filtering input data converted from an optical signal converting input data from a serial form into a parallel form, permutating data symbols from the input data to form K clusters, passing the permutated data to an adder and multiplier for each cluster; and adding output of all K multipliers together to form an output.
