[matlab] OFDMA-resource-Allocation(matlab) DL : 2: 基于OFDMA系统的多用户资源分配算法，论文配备MATLAB代码，入门的好教材。-— Orthogonal Frequency Division Multiple Access (OFDMA) basestations allow multiple users to transmit simultaneously on different subcarriers during the same symbol period. This paper considers basestation allocation of subcarriers and power to each user to maximize the sum of user data rates, subject to constraints on total power, bit error rate, and proportionality among user data rates. Previous allocation methods have been iterative nonlinear methods suitable for ofine optimization. In the special high subchannel SNR case, an iterative root-nding method has linear-time complexity in the number of users and N logN complexity in the number of subchannels. We propose a non-iterative method that is made possible by our relaxation of strict user rate proportionality constraints. Compared to the root-nding method, the proposed method waives the restriction of high subchannel SNR, has signicantly lower complexity, and in simulation, yields higher user data rates.

[VHDL-FPGA-Verilog] Process_Algebra_www.softarchive.net DL : 0: Research towards meeting the higher demands for higher data rates was the main reason for the birth of an evolution technology towards the 4th generation mobile communication systems. This evolution to the current 3rd generation UMTS systems was given the name E-UTRA/UTRAN Long Term Evolution (LTE) by the 3GPP. This paper analyzes the requirements for this evolution and evaluates the performance of the OFDM-LTE system under different propagation impairments (AWGN and multipath fading channels involving Pedestrian and Vehicular scenarios) in terms of bit and symbol error rates (BER and SER) for different modulation formats.

[Other systems] BERforQAM DL : 0: BER of QAM at Different bitrates, The resulting bit error rate the Monte Carlo simulation for the different QAM bit rates (4 to 1024) have been exported to the Matlab workspace as a vector of error values for each bit rate versus the noise power spectral density (Eb/No) variations. The figure illustrates the fact that at higher transmission bit rates, the error in the received signal increases. Therefore, it becomes a tradeoff between the transmission speed and the accuracy of the transmitted data. The increase in the error or distortion in the received signal may add to the complexity of the receiver design in order to recover the original signal or information.-BER of QAM at Different bitrates, The resulting bit error rate the Monte Carlo simulation for the different QAM bit rates (4 to 1024) have been exported to the Matlab workspace as a vector of error values for each bit rate versus the noise power spectral density (Eb/No) variations.
