A Review on analysis of Non-linearities.rar - Spectrum efficiency and channel robustness are the main key features of orthogonal division multiplexing which one is used in broadband communication. OFDM belongs to multicarrier modulation which carries the data information over many subcarriers. OFDM, a modulation as well as multiplexing technique is the origin of several telecommunications standards counting digital terrestrial television

coherent-optical-OFDM-with-constellation-expansio - High-order modulation formats and advanced error correcting codes (ECC) are two promising techniques for improving the performance of ultrahigh-speed optical transport networks. In this paper, we present record receiver sensitivity for 107 Gb/s CO-OFDM transmission via constellation expansion to 16-QAM and rate-1/2 LDPC coding
DVB-T-CHANNEL-CODING-IMPLEMENTATION.rar - The paper deals with the Matlab implementation and simulation of channel coding and modulation of DVB-T (Digital Video Broadcasting – Terrestrial). Transport stream multiplex adaptation and randomization for energy dispersal, outer coding and interleaving, inner coding and interleaving, constellation and mapping blocks of encoder and decoder are implemented. Channel encoder and decoder
OFDM-Signal-Improvement-Using-Radio-over-Fiber-fo - OFDM as a modulation technology, it transmit over both wireless and optical channel, and it distribute the data over a large number of subcarrier can be overlapping. It achieved RF signal for the long haul transmission using RoF system.
Precoding-and-Reed-Solomon-Coding.rar - Designing energy efficient mobile communication system is the main challenge for the LTE researchers due to increasing of users and their demands in accessing broadband services on mobile phones. High data rate, reduced Bit Error Rate (BER) and low Peak to Average Power Ratio (PAPR) are the requirement of the current telecommunication technology in both uplink and downlink. In this paper, various modulations techniques (QPSK, BPSK and QAM) and pre-coding schemes (DPC, THP, and RS) are proposed to analyze the uplink characteristics

khamy.rar - bandwidth efficiency of shannon limit - Here, wavelets are used in Orthogonal frequency division multiplexing. Wavelets are small waves having amplitude increase starting zero and reduces back to zero. In conventional OFDM, IFFT is used at the transmitter side and FFT is used at receiver. In case of Wavelet OFDM, IFFT is replaced with IDWT and DWT is used instead of FFT. In OFDM cyclic prefix is added to reduce inter channel interference and inter carrier interference. By using wavelet transform, cyclic prefix is not needed. Hence, it has high spectral efficiency. Wavelet transform the signal one domain to time and frequency domain.
