By using these different parameters we try to overcome the near far problem in the CDMA network. Network cellule area cover the small part to reduced the near far problem in the network. P-CDMA is used to reduce the near far problem in the network.Key words: CDMA, P-CDMASonia Devi...
The central issue in direct-sequence code-division multiple-access (DS-CDMA) ad hoc networks is the prevention of a near-far problem. This paper considers two types of guard zones that may be used to control the near-far problem: a fundamental exclusion zone and an additional CSMA guard zon...
