说明：Matlab Simulink 2012a Model shows how this complex OFDMA technique works on the simple Uplink example. Model consists of two users (transmitters) who send bursts of data to a base station (receiver). Channel is clear, and no correction coding is used, for the sake of simplicity. Transmission is in base band, and is considered synchronized. Bursts of data are raw, without control bits. All of these: AWGN noise or fading, correction coding, transmission in bandpass channel, and control bits can be added easily. For the simulation of asynchronus link, i don t know.

说明：This paper presents the OFDMA system based on FRFT technique.

说明： Additionally, LTE supports operation both in paired and unpaired spectrum (FDD and TDD) using channel bandwidths of approximately 1.4MHz up to 20MHz. The frequency domain scheduling can be done in OFDMA. One of the main challenges in OFDMA is the high peak-to-average radio of the transmitted signal, which requires linearity in the transmitter. The linear amplifiers have low efficiency therefore, OFDMA is not an optimized solution for a mobile uplink where the

说明：Orthogonal Frequency Division Multiplexing (OFDM) has been adopted by most wireless and wired communication standards these include wireless Local Area Networks (LANs) HyperLan2, 802.11a, broadband wireless(802.16) and lately the 802.15.3c for millimetre wave communications. In parallel, Field-Programmable Gate Arrays (FPGAs) have become an alternative for the implementation of those standards, due to their increased capabilities (speed and resources). This work introduces the design and performance evaluation of an OFDM transceiver, implemented on a FPGA platform for applications on a wireless millimetre wave radio system, operating around 60GHz.

By implementing these new modulation and algorithm to the system the throughput performance is increased as compared to previous technologies tested.
