(GPS is straight forward: Only 33 satellites) Say, there are N=100 million CDMA handsets worldwide. CDMA uses 128 bit Gold codes, so each BTS can support K=128 simultanuous users (and more by increasing interference). What, when and how do the N cellphones get their codes assigned?
What are CDMA codes?
The basic principle is that different CDMA codes are used to distinguish between different users. Forms generally used are direct sequence spread spectrum modulation (DS-CDMA), frequency hopping or mixed CDMA detection (JDCDMA). Here, a signal is generated which extends over a wide bandwidth.
How does CDMA recognize a signal?
For this reason, CDMA is able to recognize by decomposing each of the path to reach with the time difference. From this, it receives a different paths of signal each one separately, by summing later, it can prevent signal degradation. This is called as the RAKE receiver.
