BER Analysis of CDMA, OFDM & UVW System Using SIMULINK

CDMA (Code Division Multiple Access), OFDM (Orthogonal Frequency Division Multiplexing) and UWB (Ultra Wide Band) are t h e most developing technologies in modern mobile communication. OFDM is a parallel transmission scheme, where a high-rate serial data stream is split up into a set of low - rate sub streams, each of which is modulated on a separate subcarrier. Increasing the number of parallel transmission reduces the data rate that each individual carrier must convey and that lengthens the symbol period. Most third generation mobile communication systems are using CDMA as their modulation technique. Prior to the recent industry boom, the most common UWB system implementation is impulse radio, where ultra-short baseband pulses are used with a variety of modulation schemes to transfer data.
