Overview of Software Defined Radio on Jacinto™ Infotainment Devices


February 22, 2017

This training describes the basic functions, as well as technical challenges, of terrestrial radio reception in a vehicle.

TI’s Jacinto™ Infotainment processors provide “out of box” support for the primary digital radio standards in U.S. (HD Radio™) and in Europe (“Digital Audio Broadcasting”, or DAB).

The processor use a “Software Defined Receiver” (SDR) approach to implement a world-wide radio solution, even capable of feature upgrades without hardware changes.

Jacinto SDR provides a large set of radio-processing features, including seamless blending between digital radio and analog radio.It also offers the flexibility to use tuner front ends from most major tuner suppliers.

Two typical configurations are described: two tuners for main audio & background scanning, or adding a third tuner to extend radio quality/range, using “Maximal Ratio Combining” (MRC).

TI’s powerful C66x DSP on Jacinto Infotainment processors can also be used for audio post-processing of the decoded audio.
