[Program doc] qam8_nograycode DL : 0: An 8-QAM communications channel simulation in Simulink, constructed from a 16-QAM model and using an I,Q correlation receiver. QAM (quadrature amplitude modulation) is a method of combining two amplitude-modulated (AM) signals into a single channel, thereby doubling the effective bandwidth. QAM is used with pulse amplitude modulation (PAM) in digital systems, especially in wireless applications. In a QAM signal, there are two carriers, each having the same frequency but differing in phase by 90 degrees (one quarter of a cycle, from which the term quadrature arises). One signal is called the ‘I’ signal, and the other is called the ‘Q’ signal. Mathematically, one of the signals can be represented by a sine wave, and the other by a cosine wave. The two modulated carriers are combined at the source for transmission. At the destination, the carriers are separated, the data is extracted from each, and then the data is combined into the original modulating information. -An 8-QAM communications channel simulation in Simulink, constructed from a 16-QAM model and using an I,Q correlation receiver.

[Algorithm] cordic_atan DL : 1: 用verilog语言实现计算反正切函数，在软件无线电中解调PM/FM中使用的尤为频繁。上传的压缩包是modelsim工程，基于6.5c,里边包含一个完整的PM波产生以及解调过程的matlab文件仿真，并取其中间的I和Q支路做为verilog文件的输入，并将其借条输出与MATLAB实际解调输出作比较。鉴相器的设计基于CORDIC算法，其精度取决于迭代的深度。由于工程实际运用只需要解调出atan值，并不需要绝对的值，所以并没有给予加权，需要的同学可以自己加上。-Calculated using verilog language arc tangent function, the software radio demodulation PM/FM is particularly used frequently. From the archive is modelsim project, based on 6.5c, inside the PM contains a complete demodulation process of wave generation and simulation matlab file, and whichever is the middle of the I and Q branch verilog file as input, and its IOU demodulated output and actual output of MATLAB for comparison. Phase detector design is based on CORDIC algorithm, its accuracy depends on the iteration depth. As the practical application of engineering demodulated atan value only and does not need absolute value, and there is no weight given to the need of the students can add their own.

[Graph Recognize] Extract-I(q)-vs DL : 0: This function requires the input of a 2D matrix containing intensity values (double) corresponding to the x-ray scattering image (‘imagemat’). It returns I(q) vs. q in matrix ‘IvsQ’. It loads the experimental parameters saved in A.1. Start and end pixel counts can be adjusted as needed. It is important to resize matrices ‘allpixels’ and ‘sortedpix’ accordingly.
