  • Advantages And Disadvantages Of Code-Division Multiple Access (CDMA)

    Code-division multiple access (CDMA) Discussion of CDMA Code-division multiple access (CDMA) is a multiple access method used by different types of radio communication technologies. Direct-sequence spread spectrum signals uses CDMA which allow more than one user to share a channel. CDMA is a form of multiplexing which allows many signals to occupy a transmission channel and optimizing the use of available bandwidth. Therefore, the receiver separates the signals from the users by cross…

  • Analysis Of Qos Analysis Of 4G And 3G

    QoS Analysis of 3G and 4G systems Abstract— The cellular communication system performance is improved by increasing channel capacity and spectrum efficiency. Spectral efficiency (SE) is a key factor in the design of cellular communication system as it quantifies how well the limited frequency spectrum resource is utilized. The efficient use of spectrum is analyzed in terms of coverage area, capacity and reuse distance. OFDMA is a very potential multiple access technique, which will be the…
