| 摘 要： | DRM(Digital Radio Mondial)规定了一种应用于30MHz以下地面广播的数字声音广播系统，能够高质量地传输声音、数据及静止图片等。DRM系统采用正交频分复用和多电平调制技术，为保证接收信号质量，在接收机中需要进行信道均衡。根据DRM系统发射信号的特点，设计了一种信道估计算法，兼顾了复杂程度和均衡精度，并且对载波频偏不敏感。

| Abstract: | DRM (Digital Radio Mondiale) system is a kind of broadcasting system for terrestrial broadcasting below 30 MHz. It can transmit high quality audio, data related to program, other data and still picture. DRM system adopts OFDM and QAM techniques, so channel equalization needs to be used in DRM receiver. Considering both complexity and precision, a method of channel estimation is designed in this paper, which makes use of gain references that are grid distributed in time-frequency domain and is insensitive to carrier frequency offset. |
