Abstract

This paper presents a 10Gb/s concatenated BCH encoder of super FEC. The concatenated BCH encoder module contains 32 BCH column encoder groups and 2 BCH row encoder groups. To achieve high speed, parallel encoding technique is employed. In addition, some optimization methods such as sub-expression sharing and tree-based structure are also adopted to balance the gates´ fanout and reduce the delay. The concatenated BCH encoder has been designed and realized in the FPGA. The simulation results show that the data rate of 10Gb/s can be realized under the working frequency of 156Hz.
