    摘要： A Digital Radio Mondiale (DRM) receiver and demodulation method includes an analog and digital separation filter for filtering and separating a DRM-encoded signal and a non DRM-encoded signal from a composite RF signal received at the receiver. The DRM receiver includes a programmable downsampler and a programmable N-point Fast Fourier Transform (FFT) to recover and demodulate the OFDM symbols in a received DRM-encoded RF signal. The received signal is digitally sampled at a rate operably integer downsampled to achieve a number N samples in the useful portion of the OFDM symbol for input to an N-point FFT, where N equal to a power of two. The downsampling rate and size (N-points) of the FFT depend on the DRM encoding and transmission parameters, notably the robustness mode and spectrum occupancy. The structure and operation of the receiver in this manner simplifies the design and reduces the required filter order of the analog and digital separation filter.

    摘要翻译： 数字无线电广播（DRM）接收机和解调方法包括模拟和数字分离滤波器，用于从在接收机处接收的复合RF信号过滤和分离DRM编码信号和非DRM编码信号。 DRM接收机包括可编程下行采样器和可编程N点快速傅里叶变换（FFT），以在接收的DRM编码RF信号中恢复和解调OFDM符号。 接收到的信号以可操作的整数下采样的速率进行数字采样，以在OFDM符号的有用部分中实现N个采样，以输入到N点FFT，其中N等于2的幂。 FFT的下采样率和大小（N点）取决于DRM编码和传输参数，特别是鲁棒性模式和频谱占用。 以这种方式，接收机的结构和操作简化了设计，并减少了模拟和数字分离滤波器所需的滤波器顺序。
