摘要

本文提出了一种新的盲帧同步和相位偏移估计算法，该算法可以应用于任何使用二进制相移键控(BPSK)调制信道编码的数字传输方案。所述估计器基于使用所述码的奇偶校验矩阵获得的所述接收码字的综合征元素的计算。在提出该方法后，我们通过将其应用于一些低密度奇偶校验码和卷积码来评估其性能。该性能通过绘制假帧同步的概率和均方估计误差(MSEE)与信噪比(Eb/N0)的关系来衡量。

Blind frame synchronization and phase offset estimation for coded systems

In this paper, we present a new algorithm of blind frame synchronization and phase offset estimation that can be applied to any digital transmission scheme using a channel coding with a binary phase shift keying (BPSK) modulation. The estimator is based on the calculation of the syndrome elements of a received codeword obtained using the parity check matrix of the code. After presenting the proposed method, we evaluate its performance by applying it to some low density parity check (LDPC) codes and convolutional codes. This performance is measured by plotting the probability of false frame synchronization and the mean squared estimation error (MSEE) versus the signal to noise ratio (Eb/N0).
