WebThe CDMA technique simply means communication with different codes. In the CDMA technique, there is only one channel that carries all the transmission simultaneously. CDMA is mainly based upon the coding theory; where each station is assigned a code, Code is a sequence of numbers called chips. WebSDMA utilizes the spatial separation of the users in order to optimize the use of the frequency spectrum. A primitive form of SDMA is when the same frequency is reused in different cells in a cellular wireless network.
