[OFDM_scramble.rar] - OFDM on the scrambler design of the personal MATLAB algorithm, more classic! Scrambling code for selecting the MATLAB program. 32 Program another recursive Matlab function called myScramble2 that takes in a from ENGIN 7 at Berkeley. Hello, Im trying to implement 802.11 scrambler/descrambler in matlab. Based on the standard, it should look sth like this: My code looks like this. Scrambler and descrambler MATLAB source code. This section of MATLAB source code covers scrambler or randomizer matlab code. De-scrambler matlab code is provided to validate the scrambler. Scrambler often referred as randomizer basically removes long stream of o's and 1's from the data. It is used in wireless transmitter and receiver chain.

Well since its homework what have you tried or thought up of? I find these problems are not just about learning the syntax but ways to get you to think of creative ways to tackle the problem.

What have you learned and what functions are you allowed to use? Putting my TA hat on maybe this hint would help. You probably know how to make a for loop, generate a random number, and take items away from an array/put things into another array. Using just these three methods would get your scrambling function.

I'll only provide an outline so your function would look something like this. Function scrambled = wordScramble(Oword) totNum = total number of letters using functions like length() or size(); while totNum does not equal 0 randindex = random number from 1 to totNum;%using the randindex to add the letter to scrambled.%using randindex remove that index from Oword. TotNum = totNum-1 end While this is one way to do it there are multiple ways to accomplish the scrambling using basic Matlab calls. Maybe use rand and loops to perform a mixing like the shell game aka Thimblerig. I'm not sure if it is the best way but one method is to write out an outline, like i have above, of what you're trying to accomplish. Free game to play now. Well, try this: string = 'abcdefghijklmnopqrstuvwxyz' scrambledString = []; while length(string)>0% Get a random location in string.

Index = randi(length(string), 1);% Append that to scrambledString. ScrambledString = [scrambledString, string(index)];% Remove that letter from string. String(index) = []; end% Show in the command window. ScrambledString In the command window: string = abcdefghijklmnopqrstuvwxyz scrambledString = fcjknpbhwaytorgqzmselvuidx Hopefully I didn't just do the entire homework question for you or you'd be plagiarizing. If it was homework, you were supposed to add the 'homework' tag to it up below your question but I didn't see that.
