DSP implementation of a DRP™ -based low cost software-defined emergency radio

Abstract

The Project25 (P25) standard was developed to serve the communication needs of emergency workers and the public safety community. Using a software-defined radio structure for emergency radio standard within the framework of an RF ASIC/SoC like Texas Instruments (TI) low cost Digital RF Processor (DRP™) chip is an important step forward to help the public safety community reduce hardware costs while achieving interoperability. In this paper, we highlight how this can be achieved using programmable digital signal processors (DSPs) which perform baseband processing.
