【摘要】 设计了一种应用于不对称业务的多用户OFDM传输方案:一帧由16个突发时隙组成,短时隙用于传输低速业务,长时隙用于传输高速业务,用户根据需要动态占用一个或多个时隙.在Xilinx Virtex 5系列FPGA中实现了该设计方案.测试证明,此方案能有效实现多径信道下的多用户通信.更多还原

【Abstract】 An OFDM scheme is designed for asymmetric services.There exist 16 time slots in one frame,with short slots for low-rate transmission,and long slot for high-rate transmission.These slots can be dynamically occupied by each user.Xilinx Virtex5 FPGA is utilized to implement the design.Result shows that the scheme can effectively realize the multiuser communication in wireless multipath channel.更多还原
