Channel Models for Indoor Wireless Transmission
نویسنده
چکیده
In this paper a procedure is given for obtaining the channel impulse response for a rectangular room in terms of image sources. Exact image source strengths are evaluated using the Laplace transform formulation of the Sommerfeld problem. The coherent component of the impulse response is shown to exhibit significant variation is space. The performance of a decision feedback equalizer is examined in this context. The number of feed-forward and feedback taps required for a prescribed performance level is shown to be strongly influenced by the transmission frequency and source/receiver position.

Indoor Non-directed Optical Wireless Communications - Optimization of the Lambertian Order
For an indoor non-directed line of sight optical wireless communication (NLOS-OWC) system we investigate the optimized Lambertian order (OLO) of light-emitting diodes (LEDs). We firstly derive an expression for the OLO from a conventional Lambertian LED model. Then, we analyze the indoor multi-cell NLOS-OWC channel characteristics including the optical power distribution and the multipath time ...
