摘要

本文提出了一种改进的数字视频广播-手持(DVB-H)系统中的分散导频同步(SPS)方案，该方案检测当前接收的正交频分复用(OFDM)符号的导频模式。为了减少采样频率偏移(SFO)的影响，该方法在传统的基于相关的采样频率偏移(SPS)的基础上，采用了偏相关方法。通过计算机仿真，从同步失败概率的角度对传统的SPS算法和提出的SPS算法的同步性能进行了评价。

An Improved Scattered Pilot Detection Scheme for OFDM-Based DVB-H

In this paper, we present an improved scattered pilot synchronization (SPS) scheme in the digital video broadcasting-handheld (DVB-H) system, which detects the pilot pattern of currently received orthogonal frequency division multiplexing (OFDM) symbol. To reduce the SPS time and mitigate the influence of sampling frequency offset (SFO), the proposed SPS method is based on the conventional correlation-based SPS and adopts a partial correlation. By using computer simulation, the synchronization performance of the traditional SPS and the proposed SPS algorithms is evaluated in terms of probability of synchronization failure.
