Asynchronous random access (RA) protocols are particularly attractive for\ntheir simplicity and avoidance of tight synchronization requirements. Recent\nenhancements have shown that the use of successive interference cancellation\n(SIC) can largely boost the performance of these schemes. A further step\nforward in the performance can be attained when diversity combining techniques\nare applied. In order to enable combining, the detection and association of the\npackets to their transmitters has to be done prior to decoding. We present a\nsolution to this problem, that articulates into two phases. Non-coherent\nsoft-correlation as well as interference-aware soft-correlation are used for\npacket detection. We evaluate the detection capabilities of both solutions via\nnumerical simulations. We also evaluate numerically the spectral efficiency\nachieved by the proposed approach, highlighting its benefits.\n
