摘要
In this work, the multiple access channel (MAC) with asynchronous users is considered. Users are not allowed to cooperate together and do not have any channel side information. The code design criteria are first developed for this channel and a MAC coding scheme that verifies these criteria, i.e., delay tolerant code, is investigated. Simulation results confirms that the diversity of the proposed space-time codes is preserved in an asynchronous scenario.
