This thesis analyzes and quantiˉes the performance of adaptive orthogonal frequency division multiplexing (OFDM) systems in conjunction with single and multi antenna systems operating over frequency selective Rayleigh and Rician fading environm

Modern wireless communication systems are expected to support high data rate, allowing users to access high quality multimedia content, anytime-anywhere. To support high data rate, wideband frequency channels are required. However, frequency selectiv

在OFDM系统 中，宽带信道被分割相互重叠的窄带子信道，如果各子信道 的带宽比信道的相干带宽要小，那么信号传输就有可能在无 频率选择性衰落或者平坦衰落的信道进行。-In OFDM system The wideband channel is divided into narrowband sub-overlapping, if each sub- The bandwidth is less than the coherence bandwidth of the channe
