OFDMA resource Allocation matlab
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.)

数字频带通信系统
输入：首先输入模拟信号，给出此模拟信号的时域波形。
数字化：将模拟信号进行数字化，得到数字信号，可以选择PCM编码。
调制：可以选择简单的二进制数字调制方式。例如振幅键控(2ASK)、相移监控（2PSK）、频移键控（2FSK）、差分相移键控（DPSK）等。要求每个题目至少选择两种调制方式。有能力的同学也可以选择其它高效的调制方式?例如多进制数字振幅键控等?给出调制后信号的时域波形。
信道：假定信道属于加性高斯信道?或自行设计。
解调：相应的2ASK、2PSK、2FSK、DPSK解调，仿真获得解调输出波形。
PCM解码：给出解码后的模拟信号的时域波形，并与输入信号进行比较。
系统性能分析：比较在不同调制方式下，该数字频带传输系统的性能指标，即该系统的输出误码率随输入信噪比的变化曲线。(Digital frequency band communication system)

The Haar transform can be expressed in the matrix form as T = HIHT (inverse transform HTTH) where I is an NxN image matrix, H is an NxN transformation matrix and T is the resulting NxN transform.
For Haar transform, the transformation matrix H contains the Haar basis functions hk(x). They are defined on a continuous, closed interval, x -[0, 1] for k = 0,1,2 ...,N -1 where N = 2n.(
