Probability of error in a spread spectrum network with variable bit rate and constant chip rate

The local communications network of the future will be a single-mode fibre optic network handling voice, data, and high resolution video. A reasonable approach to the problem of interfacing the wide variety of users to such a network is by means of electrical sub-networks. This paper deals with frequency hopping spread spectrum sub-networks with user equipment (devices) of variable rates and a constant chip rate. In such a network, there can be three types of users: slow-frequency hopped, simple-frequency hopped and fast-frequency hopped users. This paper investigates the probabilities of bit losses for all three types of users in such a sub-network.
