Angle diversity and space diversity experiments on theSalton/Brawley hop

摘要

Space diversity and angle diversity experimental data that havebeen collected over a three-year period, using 64-QAM radios, on theSalton/Brawley hop in southern California are discussed. Both measureddata and simulations show that the performance of angle diversitysystems depends upon the direction of transmission on the path as wellas the polarization of the signal. While this may be true for spacediversity, the effects of a finite spatial correlation length and asmall signal-to-noise ratio significantly reduce the sensitivity ofspace diversity to the direction of propagation on this path. Theperformance of angle diversity is shown to depend upon the method usedto implement angle diversity
