Wireless communication system with frequency selective channel OFDM modulation technique
Generally, the signal of wireless communication channels is distributed from the transmitter to the receiver in a multipath fading because of the dynamic environment in the wireless channel [1-4]. Since the multipath takes place in the wireless transmission, this means that the power of transmitted...

description | Generally, the signal of wireless communication channels is distributed from the transmitter to the receiver in a multipath fading because of the dynamic environment in the wireless channel [1-4]. Since the multipath takes place in the wireless transmission, this means that the power of transmitted signal will be transformed from the transmission point to the reception point by a huge number of paths. The spaces between the modulating carriers are equal and their values are selected to make the carriers orthogonal with each other. [...]a cyclic prefix is inserted in the beginning of each symbol in order to resist the ISI resulted from the channel effects [6-8]. [...]for upcoming-generation of mobile wireless systems, the OFDM could be the leading technique [12]. [...]the world has witnessed sinifigent efforts in this area of study, OFDM, so as to transmite data streams with high bit rate. |
