“…One problem is the associated increased Peak-to-Average Power Ratio (PAPR) in comparison with single-carrier systems [13], requiring a large linear range for the OFDM transmitter"s output amplifier. In addition, OFDM is sensitive to carrier frequency offset, resulting in Inter-Carrier Interference (ICI) [17]. form of distortion of a signal in which one symbol interferes with subsequent symbols.…”

“…The use of multicarrier code division multiple access (MC-CDMA) has recently been proposed for future wireless communication systems, and cellular networks in particular [1], due to its high data rate or spectrum efficiency over frequency-selective fading channels [2,3]. MC-CDMA combines orthogonal frequency-division multiplexing (OFDM) with CDMA to spread the data symbol in the frequency domain.…”

“…The turbo and STBC codes in CDMA performance are also appraised through minimizing complexity of receiver for multi-users [7]. In [8], a multistage receiver was designed with the help of MMSE and interference cancellation method.…”
