Description

Performing wireless communication into vehicles which are equipped with hardware devices. Here proposed software-defined radio (SDR)-based wireless communication gateway (SWICOM) which are used for vehicular wireless communication. This SDR technology uses software to perform signal processing instead of hardware devices. This approach allows the integration of multiple wireless devices into a single generic wireless gateway device. Analyze the run time performance and estimate the worst-case execution time (WCET) analysis. It is a radio communication system where components that have been typically implemented in hardware (e.g. mixers, filters, amplifiers, modulators/demodulators, detectors, etc.) are instead implemented by means of software on a personal computer or embedded system. A basic SDR system may consist of a personal computer equipped with a sound card, or other analog-to-digital converter, preceded by some form of RF front end. Significant amounts of signal processing are handed over to the general-purpose processor, rather than being done in special-purpose hardware (electronic circuits). Such a design produces a radio which can receive and transmit widely different radio protocols (sometimes referred to as waveforms) based solely on the software used.
