Design of an efficient digital down-converter for a SDR-based DVB-S receiver

2007

This paper presents the design of an area-power efficient digital down-converter suitable for broadband communication systems. The DVB-S standard has been used as a design example. It has been shown that by selecting a bandpass sampling to generate only one spectral image, the case in which the relationship between the digital carrier frequency and the sampling frequency is 1/4, not only gives the smallest area but the lowest power consumption.

Research and Implementation of Energy Dispersal Algorithm for DRM System

2020

The article investigates the randomization algorithm of the OFDM signal energy used in modern digital broadcasting systems. Transmission part of the DRM system was modeled in MATLAB/Simulink software environment, bit sequences allocation tests were conducted using the original information signal and the corresponding modulation symbols with a scrambling algorithm and without it.
