OUTPUT SNR FOR A LIMITING RANDOM ACCESS REPEATER

Abstract

The acquisition delectability parameter, also known as output signal-to-noise ratio, has been computed for unrestricted random access through an ideal hard-limiter. The method is straightforward but long - it involves multi-dimensional Fourier series and numerical integration. The results depend on many parameters, such as the number of active users, the total number of users, the input signal-to-noise ratio, the length of the address code, the cross-correlation properties of this code, and so forth. The effects and tradeoffs for these parameters are shown in a number of graphs. By and large, the conclusions compare with those of other workers and, with minor exceptions, can be deduced from the well-known linear repeater characteristics. The method given provides a tool for synthesis of random access networks, be they satellite repeaters for land, sea, or air-borne transmitters, or be they mobile radio relays concerned with accidental or intentional interference.
