JOINT TRANSMITTER AND RECEIVER MAP ALGORITHM FOR ENHANCING FILTERING TOLERANCE IN A BANDWIDTH-LIMITED SYSTEM

摘要

A system for optimizing signal quality in an optical communication system is provided including a transmitter (100) for converting digital signals to optical signals, the transmitter (100) including a transmitter digital signal processing chip (103) including a predistortion logic (105) and a transmitter look-up table (LUT) (108). A receiver (200) is operatively coupled to the transmitter (100) for receiving and converting the optical signals from the transmitter (100) to digital signals (117). The receiver (200) includes a receiver digital signal processing chip (213) including a correction logic (211) and a receiver look-up table (LUT) (208). The transmitter LUT (108) is constructed by scaling the receiver LUT (208) by a weight factor and is iteratively updated based on a weighted sum of the receiver LUT (208).
