| description |
© 2019 IEEE. The problem of unsourced random access in the asynchronous quasi-static Rayleigh fading channel is considered. A transmission scheme operating in the frequency domain is proposed. This trick allows to convert the synchronization problem to the phase shift estimation problem. The decoder utilizes treat interference as noise paired with the successive interference cancellation (TIN-SIC) approach. We present complete simulation results for the new decoder. As we are interested in energy efficiency we provide energy-per-bit vs number of active users curves and show this decoder to outperform the joint decoder from [1], [2] for both synchronous and asynchronous cases.
