文摘

This paper presents the bit rate of High Speed Downlink Packet Access (HSDPA) mode for cigar-shaped microcells deployed at tunnels. The hybrid propagation loss model with log-normal shadowing is used to calculate the signal to interference plus noise ratio taking into account the expected value and the variance of the interference. A?model of ten cigar-shaped microcells is used in the analysis. The effect of the propagation parameters on the HSDPA performance (coverage and bit rate) is studied. It is found that, with a sector transmitted power of 1 W, a sector with a range of 1?km can be deployed with the worst case propagation parameters values. It is shown that it is impossible to support more than 6 HSDPA codes for full coverage within the sector what ever the power assigned to the HSDPA service.
