Channel reassignment in TDMA systems: single-carrier transmitting, multiple-carrier hop receiving

Channel reassignment schemes are described for a time-division multiple-access (TDMA) system where a single carrier is available on the transmitting side (Tx-SC), while multiple-carriers are hopped on the receiving side (Rx-MCH). The Tx-SC/Rs-MCH TDMA system configuration is presented as being logically equivalent to a three-stage switching network. This equivalence means that rearrangement algorithms for three-stage switching networks proposed to date can be applied to channel reassignment in the Tx-SC/Rx-MCH system. The maximum number of channels that must be reassigned is shown to be M-1, where M is the number of simultaneous carriers
