摘要：
A system and method are provided for coding a frame in a packet communications system using a G.709 Digital Wrapper Frame format. The method comprises: accepting digital information; outer encoding the digital information with a Reed Solomon (RS) encoding scheme; interleaving the outer encoded information; inner encoding the interleaved information using a BCH encoding scheme; and, forming a G.709 Digital Wrapper frame including payload and parity bytes. More specifically, a standard DW superframe is formed with 122,368 bits of payload and 8192 bits of parity. The outer encoding process uses an RS(1023,1007) parent code. In one aspect, 15 groups of RS(781,765) and 1 group of RS(778,762) codewords are formed per superframe. The inner encoding process uses a BCH(2047,1959) parent code. In one aspect, 64 groups of BCH(2040,1952) codewords are formed per superframe.
