ATM无线网纠错编码研究

根据６０ＧＨｚ无线信过的特点提出对ｃｅｌｌ字头和信息字段分别采用ＢＣＨ短码和ＲＳ编码方法。另外，还提出了一种新的ｃｅｌｌ字头，包含新提出的ＢｌｏｃｋＮｕｍｂｅｒ字段，能对付深衰落造成的长突发错误，且与原ｃｅｌｌ字头兼容，理论计算表明，所提出的纠错编码方案能比较有效地将６０ＧＨｚ无线信道质量提高至ＡＴＭ技术适应的水平。指出了在６０ＧＨｚ无线信道条件下，采用ＡＴＭ技术实现无线通信网综合业务是可行的。

RESEARCH ON ERROR CONTROL CODES IN ATM RADIO NETWORK

ATM technology will be used in the future integrated services radio communica-tion network most probably. But the ATM technology is based on low channel BER. Accord-ing to the performance of 60GHz radio channel, this paper proposes a method to encode cellhead with BCH short code and cell payload field with RS code. Considering the deep degradelink which causes long bulst errors, a new cell head is also proposed here. It indudes blocknumber field, and is compatible with the original cell head, The theoretical calculating indi-cates that the error control method proposed here can improve the quality of 60GHzradio channel to adapt ATM technology effictively. This paper indicates that, it is possible torealize integraed services in radio communication network under the 60GHz radio channel condi-tion.
