Self-coherent OFDM for wireless communications

2015 IEEE International Conference on Communications (ICC), 2015
In this paper, we present self-coherent OFDM, a well-known non-coherent technique in optical communications, for wireless RF communications. Self-coherent OFDM is known to have complete immunity against phase noise using a simple RF front-end receiver and to provide a significantly higher spectral efficiency than self-het OFDM, which uses at most 50 ...

Quantum communication with three coherent states

IEEE Transactions on Communications, 1995
Quantum communication with a nonsymmetrical set of three states is considered. Some results obtained from numerical computation are presented. A model for quantum detection called "near optimum", similar to the binary case, is studied. Calculations of error probability in detection schemes subject to information criteria are performed and discussed ...

The RACE to coherent communication

Physics World, 1991
Most optical communications systems use only a fraction of the enormous transmission capacity of optical fibre. Now an EC-funded consortium has built a demonstrator capable of carrying 10 digitised television signals along fibre by the technique of multi-channel coherent optical transmission.

Community, Coherence, and Inclusiveness

2003
This paper develops a theory of schools as communities. It argues that the key to a school that is a community is that such schools are rooted in something I call a Shared Educational Project. An SEP is a constitutive vision of the nature of a good education that involves public ends requiring cooperation to achieve.
