Performance enhancement of network interface module in high definition receivers

Abstract

Network Interface Module (NIM) is a front-end receiver block, which interfaces incoming signals from outside world in to the High Definition (HD) Radio Frequency (RF) receivers. In most of the cases, NIM receives only one type of signal and down converts RF in to Intermediate Frequency (IF). In modern receivers there could be a separate block for Tuner and demodulator or there could be a single integrated block which acts as network interface module. The flexibility of the design and the cost impact are the two major components need to be taken in to consideration while finalizing the architecture of the HD receivers. This research paper explores the modularity concept in the front-end block of receivers which will helps to enhance the performance of the receivers as and when required. Capability to perform multiple tasks at NIM and there by enhancing the performance of HD receivers is discussed in this research paper.
