Abstract :
This paper describes a line-of-sight (LOS) channel simulator that can be used for the laboratory evaluation of microwave radios. The simulator has a unique design, utilizes state-of-the-art microwave circuitry, and is completely under computer control. The hardware and software design concepts incorporated in the simulator are described. Results from tests conducted on a military microwave radio are presented. The results show the sensitivity of an unprotected radio to small changes in amplitude distortion of the received signal. Static m-curve signatures are also presented. The need to simulate the dynamics of frequency selective fading is described. Small changes to the simulator which will provide such dynamic operation are planned.
