Abstract

The safety warning system (SWS) is an inexpensive, low-power, point-to-point communications link designed for intelligent transportation systems' in-vehicle signing applications at 24.1 GHz. The transmitted bandwidth of the SWS signal was analyzed, and the theoretical results were compared with measured data. The SWS meets Federal Communications Commission bandwidth requirements under all operational conditions. Additionally, because the system typically operates in a cluttered roadway environment, an upper bounds on the bit error probability is modeled under non-line-of-sight conditions. The SWS uses a continuous-phase binary modulation technique. The bit error probability is derived using a maximum likelihood receiver receiving a Rayleigh-distributed signal under additive white Gaussian noise conditions.
