摘要： 为减少多信道数据广播环境中的多信道平均延迟时间，提出一种基于贪心策略的多信道数据广播调度算法，将数据项合理地分配到各信道，最小化多信道数据项平均访问时间，在每个信道内采用近似最优的Log-time算法。实验结果表明，在不同的系统环境下，该算法都能够达到近似最优的性能。

Abstract: In order to reduce the multi-channel average delay time in multi-channel data broadcast, this paper proposes a multi-channel data broadcast schedule algorithm based on greedy strategy, a multi-channel data allocation method that rationally allocates data items to different channels in order to minimize the Multi-channel Average Expected Delay(MCAED). And within each channel, the Log-time algorithm which is supposed to be optimal in single channel is adopted. Experimental results show that the algorithm can get the near-optimal solution under a variety of circumstances.
