Description: 直扩码分多址DS-CDMA是利用高速的WALSH正交码序列作为地址码，与多用户信息数据相乘得到信息数据的直接扩频信号，再经过BPSK调制后发送出去，经过AWGN无线信道的传输后，在接收端与本地产生的地址码进行相关检测，从中将地址码与本地码一致的用户数据选出，把不一致的用户数据删除。-DS-CDMA DS-CDMA is the use of high-speed WALSH orthogonal code sequences as address code, with multi-user information data has been multiplied by the direct spread spectrum data information signal, and then after a BPSK modulated sent through AWGN channel after transmission, at the receiving end with the locally generated address code associated Detect, which will address code with local codes consistent user data elected to delete user data inconsistencies.

Description: This function generates Walsh Codes. The difference between this function and other functions available to generate walsh code is :
1. you can call this function directly in your script, you will have to pass only the value of a (length of code is 2 ^ a)
2. this function can return you both the walsh matrix and randomly selected row (you may need just one sequence for your script)
for usage details refer to file.
syntax: var = walshcode(x)
x = (0, 1, 2, 3, 4, ....)
==> length of code y = 2 .^ x = (1, 2, 4, 8, 16, ....)
by default the var will be a matrix (y x y) for getting any one sequence go to the file and invoke another built in function by removing (refer file)-This function generates Walsh Codes. The difference between this function and other functions available to generate walsh code is :

Description: The function implement the 1D sequency(Walsh) ordered fast Walsh-Hadamard transform which can be used in signal processing, pattern recongnition and Genetic alogorithms.
This algorithm uses a Cooley-Tukey type signal flow graph and is implemented in N log2 N additions and subtractions. Data sequence length must be an integer power of 2.
The inverse transform is the same as the forward transform except for the multiplication factor N. This can be easily achieved by deleting the last line i.e. x=inv(N)*x
Example:
x=[1 2 1 1]
W=FWHT(x) -The function implement the 1D sequency(Walsh) ordered fast Walsh-Hadamard transform which can be used in signal processing, pattern recongnition and Genetic alogorithms.

Description: Walsh-Hadamard codes are mutually orthognal codes,
thus when used in synchronous CDMA, the interference between users is zero.
This programm generates Walsh-Hadamard codes and also checks the orthogonality.
You can change the code length by changing value of "code_length" at the top of program
