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。
According to the characteristics of 60GHz wireless signal over the cell prefix and information fields were used BCH short code and RS encoding method. In addition, a new cell prefix, including the newly proposed BlockNumber field, is proposed to cope with long burst errors caused by deep fading and is compatible with the original cell prefix. Theoretical calculations show that the proposed error correction coding scheme Can effectively improve the quality of 60GHz wireless channel to adapt to the level of ATM technology. Pointed out that in the 60GHz wireless channel conditions, the use of ATM technology to achieve wireless communication network integrated services is feasible.
