Under the assumptions of sparse and frequency-selective Rician fading channel and non-white correlated Gaussian ambient noise the authors derive an expression for channel capacity and demonstrate the dependency on channel parameters such as the number location and power delay profile of significant taps as well as environmental parameters such as distance temperature salinity pressure and depth. Then the authors use this expression to determine the optimal carrier frequency input signalling and bandwidth for capacity maximisation.eninfo:eu-repo/semantics/openAccessUnderwater acoustic communicationIntersymbol interferenceRician channelsGaussian noiseChannel capacityInformation theoretical performancePoint-to-point single-carrier underwater acoustic systemFrequency-selective underwater channelIntersymbol interferenceSparse frequency-selective Rician fading channelNonwhite correlated Gaussian ambient noiseChannel capacity maximisationPower delay proflleEnvironmental parameterOptimal carrier frequencyArticle25992610158WOS:00034289860000210.1049/iet-com.2014.00832-s2.0-84907606028N/AQ2
