Abstract

Channel reassignment schemes used in multiple carrier hopping time-division multiple access (MCH-TDMA) systems are described. In MCH-TDMA systems channels are identified by two degrees of freedom: carrier frequency and time slot. The overlap-chain concept in which related calls from the same transmitting station to the same receiving station are grouped into contiguous streams is introduced. Using this concept, one channel can always be assigned to a call blocked due to inefficient assignment by reassigning channels to calls in progress within two or three time slots. A channel reassignment algorithm called OVERLAP-CHAINING which provides efficient means to reassign channels to calls in progress is proposed
