Carrier sense multiple access with collision detection for FH/FSK spread spectrum mobile packet radio networks

The performance of nonpersistent CSMA-CD protocol for the FH/FSK Spread Spectrum mobile packet radio network (MPRNET) is studied. The mobile radio network link is modeled as consisting of separate and independent message channel and acknowledgement channel. Probability of block error for slow Rayleigh fading is derived for FH/FSK scheme in the presence of partial-band noise interference. The modified expression for the channel throughput is derived for the CSMA-CD protocol in the context of ground mobile radio channel employing FH/FSK Spread Spectrum Communication. The throughput performance of CSMA-CD and its dependence on such key system parameters as the offered channel traffic, Collision recovery time, channel capacity, packet transmission time, and signal-to-noise power ratio are provided.
