Thesis Cdma System Types Of Ap Lang Essays
This recorded signal was then played back and recorded using the sound card of a PC. Most third generation mobile phone systems are proposing to use Code Division Multiple Access (CDMA) as their modulation technique.
For this reason, CDMA was also investigated so that the performance of CDMA could be compared with OFDM.
In this thesis a signal simulator was implemented according to the physical layer specification of the IMT-2000 WCDMA system.
The signal is further corrupted by AWGN at the front end of the receiver.
Simple rake diversity combining is employed at the receiver.
The data is transmitted in a frame by frame basis through a time varying channel.
The transmitted signal is corrupted by multiple access interference which is generated in a structured way rather than treating it as Additive White Gaussian Noise (AWGN).
