摘要：

Channel segregation was previously proposed as a self-organized dynamic channel assignment. Its performance has been examined by applying it to FDMA systems. This paper discusses its application to the TDMA/FDMA or mulitcarrier TDMA system. Spectrum efficiency of the TDMA/FDMA cellular system deteriorates due to the problem of unaccessible channel: a call can be blocked in a cell even when there are idle channels because of the restriction on simultaneous use of different carrier frequencies in the cell. This paper shows that channel segregation can resolve this problem with a small modification of its algorithm. The performance of the TDMA/FDMA system with channel segregation on the call blocking probability versus traffic density is analyzed with computer simulation experiments. The effect of losing the TDMA frame synchronization between cells on the performance is also discussed.
