Code division multiple access (CDMA) is a channel access method used by various radio communication technologies. CDMA is an example of multiple access, which is where several transmitters can send information simultaneously over a single communication channel. This allows several users to share a band of frequencies (see bandwidth). To permit this to be achieved without undue interference between the users CDMA employs spread-spectrum technology and a special coding scheme (where each transmitter is assigned a code). Each user in a CDMA system uses a different code to modulate their signal. Choosing the codes used to modulate the signal is very important in the performance of CDMA systems. The best performance will occur when there is good separation between the signal of a desired user and the signals of other users.

Perform rotation, translation and scaling on any image using MATLAB. The function has five inputs. These include at the first place the image which is to be rotated, translated and scaled. The second includes the scale factor. Scale factor less than 1 results in compression whereas that more than 1 results expansion. The value in this field cannot be 0.The third includes rotation which can have values like 0,10 30,etc. The fourth is x translation value and the fifth being the y translation value. The output images will be a combination of all the inputs provided.
