Abstract :
The paper proposes a channel model for LOS street microcells with low antenna height base sites. This channel model assumes some virtual source point (VSP) and locates then at the intersection points along the LOS street and building walls under the LOS condition, and so is developed as a location-specific model. The predicted delay spread has excellent agreement with experimental results when the VSP attenuation constant is 0.07. Using the proposed model, the bit error rate (BER) performance of π/4-shift DQPSK transmission with and without diversity reception can be evaluated. Its effectiveness is confirmed by field experiments
