| Abstract | Abstract. In this research work, a new channel assignment technique that takes into consideration the location of the user that could be found anywhere in the cellular area is developed, simulated and compared with some bench mark techniques. The scheme is applied on 49 hexagonal cells. A design of a locking parameter in case of borrowed channels is made which acts as an indicator to locking or unlocking of the identical channels in co-channel cells. This scheme has maintained the traffic quality of the borrowed channel, without reducing its power. As a result, this scheme is found superior in performance over all the conventional channel assignment schemes, like the Fixed Channel Assignment (FCA) and the Borrowing Channel Assignment (BCA) schemes, in the sense of utilizing the available spectrum efficiently and thus increasing the capacity of the cellular system. |
