An Analytical Approach for Efficient OFDM Modulator and Demodulator Communication Systems Based On Discrete Hartley Transform
The main drawback of OFDM is its high peak to average power ratio (PAPR). High PAPR of OFDM makes it unusable in non-linear systems. So the clipping signals scheme is one useful and simple method to reduce the PAR. In the widely used OFDM (Orthogonal Frequency Division Multiplexing) systems, the FFT and IFFT pair are used to modulate and demodulate the data constellation on the subcarriers. Thi...
متن کاملPerformance Improvement of OFDM Using Subcarrier Frequency Diversity
Orthogonal Frequency Division Multiplexing is a key contender for broadcasting standards, due to its immunity towards multipath fading and ease of implementation. Here a novel scheme to exploit the frequency diversity within OFDM subcarriers has been proposed which further increases the bit error rate performance. The diversity is achieved by circularly shifting the OFDM subcarrier coefficients...
متن کاملPAPR Reduction Using Pre - Coder Based Discrete Hartley Transform in Optical OFDM Systems
In many wireless network applications Optical Orthogonal Frequency Divison Multiplexing (O-OFDM) plays an important role. It is a promising modulation technique for handling rapidly growing internet traffic. But higher peak to average power ratio (PAPR) is a major drawback in O-OFDM systems, which in results increases the complexity of digital to analog converters (DAC) and analog to digital co...
متن کاملAn OFDM Receiver with Frequency Domain Diversity Combined Impulsive Noise Canceller for Underwater Network
In order to explore marine natural resources using remote robotic sensor or to enable rapid information exchange between ROV (remotely operated vehicles), AUV (autonomous underwater vehicle), divers, and ships, ultrasonic underwater communication systems are used. However, if the communication system is applied to rich living creature marine environment such as shallow sea, it suffers from gene...
متن کاملA Novel Comb-Pilot Transform Domain Frequency Diversity Channel Estimation for OFDM System
Due to implementation complexity, the transform domain channel estimation based on training symbols or comb-type pilots has been paid more attention because of its efficient algorithm FFT/IFFT. However, in a comb-type OFDM system, the length of the channel impulse response is much smaller than the pilot number. In this case, the comb-pilot transform domain channel estimation only works as inter...
