Abstract


The future cellular wireless network is expected to support a large variety of multimedia traffic in downlink. Orthogonal Frequency Division Multiple Access (OFDMA) technique using adaptive modulation and coding technique can increase the system capacity many fold. In this paper, the performance analysis of an OFDMA system utilizing an efficient resource allocation method, called Two Stage Rate Adaptive (TSRA) algorithm is studied. Considering wide variation in Signal to Interfering Noise Ratio (SINR) dynamically between 3 to 26 dB in Rayleigh channel, and randomly mixing of four categories of multimedia traffic, it is observed that the difference between analytical and simulated average capacity of the system gets smaller as number of user increases, and at one point the simulated average system capacity exceeds 6 b/s per Hz. Apart from spectral efficiency, Bit Error Rate (BER), and delay performance of the proposed system is evaluated here.
