- Description
- This paper addresses the design of protograph low-density parity-check (LDPC) codes for an asynchronous random access (RA) scheme. At the receiver successive interference cancellation (SIC) is assumed to recover packets subject to Gaussian interference and to remove their replicas from the received signal. Since the interference typically affects the beginning or the end of a packet we provide a dedicated code design resulting in gains w.r.t. standard channel codes. The benefit of the proposed codes is illustrated in terms of packet error rate versus channel load results. A gain of 0.1 in supported channel load at a packet loss rate of 10⁻² is shown.
