Measured characteristics of 800/900 MHz mobile radio channels with high-angle propagation through moderately dense foliage / by R.J.C. Bultitude. : Co24-3/7-1398-1986E-PDF

"The digital transmission capacity of randomly fading multipath radio channels is limited to that for which the bandwidth of transmission is much less than the coherence bandwidth (Bc) of the channel. It is therefore important for system design purposes to determine Bc in propagation environments where the use of digital radio systems is planned. This report details experiments that were conducted under conditions similar to those which would be typical on 800/900 MHz band satellite-mobile channels in rural environments. The impulse response functions of measured channels were estimated by operating a pseudo-noise channel probe from a 65 m tower through deciduous trees to a receiver at close range. Measurement results include: channel impulse response estimates, angle of arrival analyses, envelope fading statistics, and double-sided frequency correlation plots. Comparisons are made between channel characteristics during the summer and during the autumn when the leaves have fallen from the trees. Estimates of digital channel capacity limitations are also given"--Abstract, page 1.
