Modern Random Access for Satellite Communications [article]

Federico Clazzer
2017 arXiv   pre-print
In the first part an slot- and frame-asynchronous RA scheme adopting replicas, successive interference cancellation and combining techniques is presented and its performance analysed.  ...  The comparison of both slot-synchronous and asynchronous RA at higher layer, follows.  ...  While orthogonal schemes are efficient when the scenario is static, i.e. the number of transmitters and their datarate requirements are constant, RA is particularly indicated for very dynamic situations  ...

Managing Interference Correlation Through Random Medium Access
