O knihe
The main goal of intelligent transportation systems (ITS) is to improve traffic efficiency and mobile safety. The Dedicated Short Range Communication system (DSRC) standard based inter-vehicle communications system plays a key role in ITS [1]. In October 1999, the Federal Communications Commission (FCC) allocated the frequency spectrum between 5.850 and 5.925 GHz for DSRC,which will enable vehicles to communicate with the road infrastructure,and allows for a large number of ITS applications. This provides an opportunity for automakers, government agencies, and related commercial entities to improve highway safety. However, inter-vehicle communications must operate effectively within transmit power limits and under received signal strength ¿uctuations and Doppler spread. Conventionally, Convolutional coding was employed for forward error correction (FEC);however,in this book, we consider DSRC performance using Low Density Parity Check (LDPC) codes and Quasi-Cyclic (QC)-LDPC codes under different channel conditions. Results show that a QC-LDPC code provide an attractive trade off between performance and complexity, and should be considered as an alternative for DSRC systems.
