Constant modulus orthogonal frequency division multiplexing
2010 - MILCOM 2010 MILITARY COMMUNICATIONS CONFERENCE, 2010Orthogonal frequency domain multiplexing (OFDM) is the signal format of choice for spectrally efficient communications over time-invariant, frequency-selective channels. OFDM has a large peak-to-average power ratio, however, which makes it incompatible with transmitter non-linearities {e.g., saturated power amplifiers (PAs)). Conversely, single-carrier

Coded Orthogonal Frequency Division Multiplex (COFDM)
2010Almost from the beginning of the electrical transmission of messages about 100 years ago, single-carrier methods have been used for transmitting information. The message to be transmitted is impressed on a sinusoidal carrier by applying analog amplitude, frequency or phase modulation techniques.

Wireless Communications and Mobile Computing, 2013
This paper analyzes the bit error rate performance of orthogonal frequency-division multiplexing systems in mobile multihop relaying channels. We considered the uplink scenario and quantified the effects of mobile channel impairments such as Doppler ...

Journal of the Acoustical Society of America, 2012
There are no commonly-agreed mathematical models for the input-output relationship of underwater acoustic channels. For each path in a time-varying multipath channel within a short period of time (e.g., one short data block), this paper proposes to use ...

Orthogonal frequency division multiplexing in distributed radar apertures
2008 IEEE Radar Conference, 2008In previous work, frequency diversity has been shown to be an effective means of exploiting distributed radar apertures. Frequency diversity allows for each transmission to be isolated and processed independently of other frequencies. This paper presents an efficient implementation of a frequency diverse distributed radars, based on orthogonal ...

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 ...

The history of orthogonal frequency-division multiplexing [History of Communications]
IEEE Communications Magazine, 2009Orthogonal frequency-division multiplexing (OFDM) is one of those ideas that had been building for a very long time, and became a practical reality when the appearance of mass market applications coincided with the availability of efficient software and electronic technologies.
