Title: Huazhong Yang: Innovator in Digital Radio Technology

Introduction

Huazhong Yang is a prominent inventor based in Peking, China. He has made significant contributions to the field of digital radio technology, particularly through his innovative patents. With a total of two patents to his name, Yang has demonstrated his expertise and commitment to advancing communication technologies.

Latest Patents

Yang's latest patents include a Digital Radio Mondiale (DRM) receiver and demodulation method. This invention features 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 that is 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 equals a power of two. The downsampling rate and size of the FFT depend on the DRM encoding and transmission parameters, notably the robustness mode and spectrum occupancy. This innovation reduces the processing and computational requirements, as well as the design complexity of the DRM receiver.

Another notable patent by Yang is a DRM receiver with an analog and digital separation filter and demodulation method. This invention includes a filter for separating a DRM-encoded signal from a non-DRM-encoded signal within a composite RF signal. Similar to his previous patent, this receiver also incorporates a programmable downsampler and a programmable N-point FFT to recover and demodulate the OFDM symbols. The design simplifies the structure and operation of the receiver, thereby reducing the required filter order of the analog and digital separation filter.
