What Is Rake Receiver? |
|
Answer» CDMA system uses a signal fast chip rate for SPREADING spectrum and it has a HIGH time resolution. 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.
