ABSTRACT

The multiple reflected rays cause severe multiple paths, and the receiver again will become dispersion-limited at higher transmit rates. Multipath reflections degrade the communication quality as well as positioning accuracy. This chapter describes the impact of multipath reflections on the positioning accuracy. Impulse response that usually characterizes the linear time-invariant system, is used to describe the multipath reflections. Simulation methods have been also proposed with different algorithms. The travelling times to the receivers are also recorded. These elements are then considered as separate transmitters, and their transmitted power is the received power degraded by the reflection coefficient. The chapter analyzes the impact of multipath reflections on the positioning accuracy in the complex indoor environment. The impulse response is analyzed by employing combined deterministic and modified Monte Carlo algorithms.
