| Popis: | One of the most prominent access techniques 10 repeal same physical channel is space division multiple access (SDMA). Repetition of beam depends on relative position of users within ceil and width of the beam. Usually two beams are preferred in dynamic cell formation but some times three beams are used for narrow beam case keeping signal to noise ration (SNR) within prescribed limit. In this paper Markovian chain is designed for two und three beams cases of SDMA traffic. A comparison is made between two cases in context of call blocking probability and probability of utilization of secondary beam. Here SDMA traffic is modelled considering for duplicate first (DF) and limited user traffic case applicable in wireless local loop. |
