Method and system for enhancing cell error ratio and cell misinsertion rate for a given cell loss ratio
Abstract:
A method and apparatus for enhancing the cell error ratio and the cell misinsertion rate for a given cell loss ratio is provided. A predetermined number, C, of ATM cells (150, 250) are packed together and encoded using a strong t-error correcting BCH block code, such as a Reed-Solomon code to produce an encoded block (162, 262). After transmission, the received data segment (156, 256) may include s errors. The data segment (156, 256) is decoded, and if s > t, decoder failure occurs with very high probability and the data segment is discarded. The CER obtained is superior to present ATM systems. The decoded block is unpacked into C ATM cells (160, 260). Optionally, the header fields (164, 264) of the C ATM cells may be decoded. In most cases where errors are present in the header, nonzero syndrome occurs with high probability, and the C ATM cells (160, 260) are discarded. The CMR obtained is superior to present ATM systems. The delivered ATM cells (160, 260) are virtually error free with very high certainty.
Abstract(Chinese):

本发明提供一种用于增强对于给定的信元丢失率的单元错误率和小区误插入率的方法和装置。 预定数目，C，ATM信元（150，250）的挤在一起，使用强叔纠错BCH码块，：诸如Reed-Solomon码编码的块（162，262），以产生编码。 传输之后，接收的数据段（156，256）可包括s-错误。 数据段（156，256）进行解码，并且如果s> T，解码器失败的具有非常高的概率发生，并且该数据段被丢弃。 获得的CE优于目前ATM系统。 经解码的块进行解包成C的ATM信元（160，260）。 OPTIONALLY，将C的ATM信元的报头字段（164，264）可被解码。 在错误存在于报头大多数情况下，非零综合征以高概率发生，且C的ATM信元（160，260）被丢弃。 获得的CMR优于目前ATM系统。 所传递的ATM信元（160，260）是几乎自由具有非常高的确定性错误。
