Abstract

Uplink cochannel interference between minimum-shift-keyed (MSK) time-division multiple access (TDMA) data packets generated by transmitters distributed uniformly over a circular area has been simulated in software. Distance-dependent attenuation, log-normal shadowing and multipath fading have been implemented. After a discussion of the radio link model and an analysis of bit error probability versus signal-to-interference ratio of a link with a single interferer, a computer model to simulate multiple interferers is presented. Numerical bit error rate (BER) results obtained from computer simulations of a TDMA radio link subject to interference front simultaneous independent transmissions, attenuation, shadowing and fading are compared with known theoretical results for the MSK channel under additive white Gaussian noise (AWGN) only. Possible improvements and future applications of the model to the problem of resource sharing between coexisting networks are suggested
