Abstract
A method for signal transmission includes generating a sequence of modulated symbols, each modulated symbol including multiple sub-carriers having respective sub-carrier frequencies, by (i) designating a first subset of the sub-carriers to serve as non-pilot sub-carriers, and designating a second subset of the sub-carriers to serve as pilot sub-carriers, (ii) modulating non-pilot information onto the non-pilot sub-carriers, and modulating pilot information onto the pilot sub-carriers, and (iii) in at least some of the symbols, setting the non-pilot sub-carriers to a first power level, and setting one or more of the pilot sub-carriers to a second power level that is higher than the first power level. The sequence of the modulated symbols is transmitted over a communication channel to a receiver.
