A sequential stitching algorithm to stitch pieces of one message together is proposed for unsourced random access communications. In a wireless network, each of active devices fragments its message and sends its encoded pieces of the message slot-by-slot to a multiple-access fading channel. An access point decodes these pieces of messages and estimates their corresponding fading coefficients, and then stitches, by clustering fading coefficients, these pieces of messages together to their original messages. Simulations show that the proposed sequential stitching algorithm has almost the same performance as an ideal stitching, even in a time-variable, memory fading channel. |
