This paper introduces the performance analysis of 802.16e OFDMA system in UL mode with respect to multi-user scheduling algorithms in frequency domain. Different scheduling algorithms - from the simplest round robin to the optimal iterative scheduling, along with practical maximum element and two-step algorithms are analyzed and compared. It is shown that multi-user scheduling in frequency domain potentially can greatly improve OFDMA system efficiency in frequency-selective broadband channel.
