Jagan naveen et al. Various Parameters have been considered as a matter of design criteria. The carrier to interference ratio CIR and bit error performance is also improved. Mobile wireless communication is the fastest growing segment of the communication industry.
The author concludes that both the techniques cut back PAPR significantly.
The analysis is done over AWGN channel. The author concludes by providing the numerical results which shows the effectiveness of the proposed relay design over the conventional AF relay design. Specifically, as a part of wireless communication system design, you can use these OFDM capabilities to analyze link performance, robustness, system architecture options, channel effects, channel estimation, channel equalization, signal synchronization, and subcarrier modulation selections.
Eonpyo Hong et al. ICI, disturbance in the orthogonality of the sub-carriers is caused due to the respective movement between transmitter and receiver which leads to Doppler frequency shifts.
In this paper, we analyze and implement a flat Rayleigh fading channel based on the inverse discrete Fourier transform IDFT. About this resource This Information Technology essay was submitted to us by a student in order to help you with your studies.
The effect of these waveforms on the performance of OFDM is analyzed. Kwanghoon Kim el al.
In the channel, Additive White Gaussian Noise is added to the signal. Various pilot based techniques have been used earlier to remove the effect of phase noise but this decreases the system bandwidth efficiency.
Power spectral density of MSK does not fall fast hence will not reduce interference completely between adjacent channels. When the OFDM signal is to be transmitted, the time domain signal is then mixed up to the required frequency.
In this paper, the author reviewed the traditional channel estimation techniques such as CFR based channel estimation, PM based channel estimation, Iterative channel estimation etc.
In order to demodulate the signal, a Discrete Fourier transform is needed.
The author shows that the proposed technique provides more gain than the traditional techniques. LTE is a long term evolution scheme of 3GPP, as a using extensively communication standards, it has higher data rate and higher quality.Simulation and analysis of dispersion compensation schemes for Gbps PDM–OFDM optical communication system.
