Orthogonal Frequency Division Multiplexing (OFDM)
2008 China-Japan Joint Microwave Conference, 2008In broadband wireless system, the signal energy is scattered and reflected from objects in the environment, components of the signal arriving at the receiver are spread out over a longer period of time than is desirable. The challenge is then to provide a high-performance reliable data link that can operate with the restricted receiver power levels ...

Orthogonal Frequency Division Multiplexing with Codebook Index Modulation
2020 28th Signal Processing and Communications Applications Conference (SIU), 2020Ultra-reliable and low-latency communications (URLLC) partake a major role in future communication systems. A possible strong candidate for future URLLC networks is sparse vector coding (SVC), which enables a superior performance in terms of bit error rate (BER).

Coded orthogonal frequency division multiplex [TV broadcasting]
Proceedings of the IEEE, 1995Technological evolution and the ever-increasing demand for higher-quality services give broadcasters a strong incentive to completely digitize their broadcasting networks. This digitization, which is already well advanced in many program production areas and transmission links, now has to be extended to complete the last link in the broadcast chain; i ...

Generalization of Orthogonal Frequency Division Multiplexing With Index Modulation
IEEE Transactions on Wireless Communications, 2015Recently, orthogonal frequency division multiplexing (OFDM) with index modulation (OFDM-IM) was proposed. By selecting a fixed number of subcarriers as active subcarriers to carry constellation symbols, the indices of these active subcarriers may carry additional bits of information.

Enhanced Orthogonal Frequency Division Multiplexing With Index Modulation
IEEE Transactions on Wireless Communications, 2017Index modulation concept has attracted considerable research interest in the past few years. As a realization of index modulation in the frequency domain, orthogonal frequency division multiplexing with index modulation (OFDM-IM) has recently been proposed, which conveys information bits through both the subcarrier activation patterns and the amplitude

Interleaved Orthogonal Frequency Division Multiplexing (IOFDM) System
IEEE Transactions on Signal Processing, 2004In orthogonal frequency division multiplexing (OFDM) systems, for every block of K data samples, an overhead of L samples of cyclic prefix (CP) or zero padding (ZP) is added to combat frequency selective channels. The code rate, which is defined as the ratio K/(K+L), is a measure of the efficiency of transmitting user information.

Orthogonal frequency division multiplexing with generalized index modulation
2014 IEEE Global Communications Conference, 2014Recently, an Orthogonal Frequency Division Multiplexing (OFDM) with index modulation (OFDM-IM) [1] was proposed. By selecting a fixed number of subcarriers as active subcarriers to carry constellation symbols, the indices of these active subcarriers may carry additional bits of information. In this paper, a generalization of OFDM-IM, named as OFDM with

Fractionally Spaced Orthogonal Frequency Division Multiplexing Systems
2007 IEEE International Symposium on Circuits and Systems (ISCAS), 2007Frequency domain equalizers using cyclic prefix have been often deployed due to their implementation efficiency and attractive performance. The design of such schemes with an L-fold fractionally spaced receiver has been recently proposed. We consider here the more generic setup where the sampler operates at L/M times the symbol rate where L > M > 1 are

Optical-orthogonal frequency division multiplexing-review
2017 IEEE International Conference on Power, Control, Signals and Instrumentation Engineering (ICPCSI), 2017We have witnessed a drastic increase in Orthogonal Frequency Division Multiplexing (OFDM) in optical community in recent years. OFDM is a type of signal modulation. OFDM divides high data rate modulating stream into many slow modulated narrowband subcarriers. Thus, it is less sensitive to frequency fading.

Orthogonal Frequency Division Multiplexing Modelling
2022This work is motivated by the need to understand the performance of Orthogonal Frequency Division Multiplexing (OFDM) and Filterbank Multicarrier (FBMC). Multicarrier techniques are widely being considered for the development of the telecommunication systems such as the Long Term Evolution (LTE) networks, 5th Generation (5G) and beyond.
