摘　　要：针对中国移动多媒体广播(CMMB)标准的网络特点,结合回波抵消与数字预失真领域的最新技术,首次提出了CMMB网络的数字直放站设计方法,并给出了硬件实现方案。经实用直放站测试验证,设计方法与实现方案满足CMMB网络覆盖的要求,对推动CMMB网络的室内与室外盲点覆盖具有很大的实用价值。In this paper, according to the characteristic of China Mobile Multimedia Broadcasting （CMMB） network, a design of CMMB digital repeater is proposed based on the new technology of echo cancelling and digital predistortion. Hardware implementation with the proposed method is presented. The The method and hardware solution are suit to requirements test results of practical repeater show that the proposed method is right. of CMMB network coverage, and are valuable to accelerate indoor andoutdoor network coverage of CMMB.
