The performance of high‐speed railway wireless communication systems is studied in the presence of co‐channel interference and imperfect channel estimation in the uplink. The authors derive exact closed‐form expressions for the outage probability and investigate the impact of fading severity. New explicit expressions are derived for both the level crossing rate and average outage duration for illustrating the impact of mobile speed and channel estimation errors on the achievable system performance. Our results are generalised and hence they subsume a range of previously reported results.
