Over the last three decades, the wireless communication technology is dominating over another technology. In this thesis, basic study of CDMA technique,is elaborated for the purpose of understanding & learning the initial concepts for the undergraduate engineering students and also those who are enthusiastic about CDMA technique. The Code Division Multiple Access (CDMA) is a digital cellular technology pioneered by QUALCOMM in USA in which signals are encoded using a pseudo-random sequence (PN sequence) - which corresponds to a different communication channels that the receiver ...

In the last couple of years, wireless communications have experienced a quick growth due to the ubiquitous mobility, super internet speed and huge multimedia services & applications. Orthogonal frequency division multiplexing (OFDM) is an emerging research field of wireless communication and finds its application where high data rate is required at low latency and better spectral efficiency. OFDM signals have a generic problem of high peak to average power ratio (PAPR) which is defined as the ratio of the peak power to the average power of the OFDM signal. The drawback of ...
