针对GPRS网络中IP信道的干扰问题,提出一种抗分组丢失算法.该算法将传输数据分段进行RS纠删编码,并采用交织技术对数据进行最优分组并传输,在纠删能力不变的同时获得近似线性的编解码时间.仿真结果表明,与原有RS编码方式相比,该算法可以更好地满足大数据编解码对实时性的要求.
針對GPRS網絡中IP信道的榦擾問題,提齣一種抗分組丟失算法.該算法將傳輸數據分段進行RS糾刪編碼,併採用交織技術對數據進行最優分組併傳輸,在糾刪能力不變的同時穫得近似線性的編解碼時間.倣真結果錶明,與原有RS編碼方式相比,該算法可以更好地滿足大數據編解碼對實時性的要求.

Aiming at the disturbance of the IP channel in GPRS network, this paper proposes a packet loss resilience encoding algorithm. The algorithm makes data transmission eutted into several sections and encoded by section based on RS erasure code, uses interleaving technology to process optimal grouping and transmission for the data, and acquires approximate linear encoding and decoding time without weakening the ability of erasure correction. Simulation results show that the algorithm can better satisfy the need of real-time for mass data coding than existing RS coding style.
