Performance Evaluation of Adaptive Modulation Based MC-CDMA System
In today’s scenario mobile phones are not used only for messaging and talking, now we use mobiles also to access internet. For that we need higher data rates. Mobiles use wireless communication channel, which is very fast varying channel. To increase the data rate we have to utilize the full channel based on the channel condition. For that we have to estimate the channel condition and based on ...
متن کاملPerformance Analysis of Dynamic Sub-Carrier Allocation Technique for Adaptive Modulation based MC-CDMA System
Multi carrier CDMA (MC-CDMA) combines the CDMA and OFDM technologies together and potentially offers the advantages of both the technologies. In frequency selective channel, the sub-carrier experiences different amplitude and phase. In frequency domain spreading, the frequency diversity is employed but the best of different sub-carrier conditions are not fully exploited. In MC-CDMA the performa...
متن کاملAdaptive Modulation of Ofdm and Mc-cdma System
Recently, intense interest has focused on the transmission techniques which can support high data rate transmission over wireless channels for applications including wireless multimedia, wireless Internet access, and future-generation mobile communication systems. However, high data rate transmission is limited by inter-symbol interference (ISI) due to the frequency selective fading in multipat...
متن کاملPerformance Analysis of Mc-cdma System Using Bpsk Modulation
Multi Carrier Code Division Multiple Access (MC-CDMA) is an attractive choice for high speed wireless communication as it avoids the problem of Inter Symbol Interference (ISI) and also exploits frequency diversity. In order to support multiple users with high speed data communications, the MC-CDMA technique is used to address these challenges. MC-CDMA experiences severe multipath fading which b...
متن کاملAn Overview of Performance Evaluation of MC-CDMA System
MC-CDMA is one of the most promising technique for future mobile communication, since it offers high bit rate and high capacity transmission. It is actually the combination two efficient techniques such as Code division Multiple Access (CDMA) and Orthogonal Frequency Division Multiplexing (OFDM) techniques. Consequently, it combines the benefits and limitation of both CDMA as well as OFDM techn...
