Signal Processing Algorithms For Dsp Implementation of Analog TV Receivers

This paper presents a novel power efficient software implementation of the NTSC analog TV receiver using the Sandbridge Technologies Software Defined Radio (SDR) platform. The Radio Frequency signal specific to a TV channel is down converted to base band and sampled at 14.318 MHz. From this stage, the entire receiver function is executed in SW, including the horizontal and vertical synchronization, and video processing. The analog TV receiver implemented in DSP can coexist with other communication protocols such as WLAN, GSM/GPRS, GPS etc. allowing analog TV broadcasting on mobile platforms.
