Abstract: This paper introduces the SC-FDE system random access scheme employing prime number Zadoff-Chu sequence as user signature, and proposes a Zadoff-Chu sequence full frequency-domain detection algorithm based on zeros padding in time-domain. Simulation result shows that the proposed algorithm can reduce the computation complexity by 90% compared to the traditional time-domain detection algorithm while maintaining same detection performance.
