Abstract

Makes possible a removal of the preamble for carrier recovery and symbol-timing recovery by storing a burst in memory with low overhead quaternary phase shift keying (QPSK) demodulation method which also effects frame efficiency improved by processed synchronization performance. In this paper, we propose the new algorithm for arc-tangent look-up table which transforms the input I, Q data by phase. This I, Q data plays an important role in demodulation and realises a demodulator with low-overhead by storing a burst in memory.

新型切线查表面积小,有线电视调制解调器系统开销低
通过使用低开销的四元相移键控(QPSK)解调方法在存储器中存储突发,使得除去用于载波恢复和符号定时恢复的序言成为可能,该解调方法还影响通过处理同步性能提高的帧效率。本文提出了对输入I、Q数据进行相位变换的切弧查找表新算法。这种I, Q数据在解调中起着重要的作用,并通过在内存中存储突发来实现低开销的解调器。
