摘要
突发模式传送系统中，前导字作为系统开销降低了数据传送效率。本文提出一种适合VLSI数字硬件实现的全数字无前导字突发模式PSK接收机方案，接收机的时钟和载波恢复均采用前向同步技术，并论述了一种新的载波频差恢复算法。仿真结果验证了算法的可行性和有效性。
The preamble signals used as overhead decrease transmission efficiency in burst-mode transmission system. In this paper，a full digital preamble-less burst-mode PSK receiver scheme is proposed. The feed-forward synchronization techniques used for symbol timing and carrier recovery are described. A new carrier frequency offset recovery algorithm is presented. . The feasibility and effectiveness on the algorithm has been verified by simulation result.
