Abstract :
Uncoordinated and packetized code time division multiple access (CTDMA) is presented. It is shown that the only difference to spread ALOHA is the demodulation technique applied in the receiver. The capacity of uncoordinated and packetized CTDMA is then determined and evaluated. In particular, it is shown that CTDMA outperforms spread ALOHA, i.e., that a linear inverse filter outperforms a matched filter in terms of single-user capacity
