摘　　要：介绍了在数据通信中用于抗突发连串错码而常常采用的交织编码技术,并针对遥测图像传输中所使用的差错控制编码———奇偶监督矩阵,提出了一种新的交织编码技术,采用这种交织编码技术,可有效克服普通交织编码时延大的缺点,并使纠错编码在一个奇偶监督矩阵中可以抵抗15位突发错误,使遥测图像传输的抗误码能力大大提高。The interweaving- coding has been introduced to deal with the burst- error in data communication, and a new interweaving - coding method is designed for the two - dimension parity - check error correction in image telemetry. The new interweaving- coding method ean get over the disadvantage of time delay effectively,by means of the new interweaving- coding method two- dimension parity check error correction be able to resist against 15 bits of burst - error,enhance the performance of error correction for image telemetry obviously.
