Prior to the discovery of the celebrated orthogonal frequency division multiplexing (OFDM), multicarrier techniques that use analog filter banks were introduced in the 1960s. Moreover, advancements in the design of perfect reconstruction filter banks have led to a number developments in the design of prototype digital filters and polyphase structures for… (More)
Although orthogonal frequency division multiplexing (OFDM) has been the dominant technology for broadband communications in the past, a number of researchers have noted the shortcomings of OFDM in frequency-selective fast-fading channels, e.g., underwater acoustic channels. Hence, alternative systems that use filter banks for multicarrier (FBMC) modulation… (More)
The Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) radio standard has adopted a special form of orthogonal frequency division multiplexing (OFDM) method for the uplink of multiple access networks. This method which is called single carrier frequency division multiple access (SC-FDMA) applies a precoding to each user data set in each… (More)
The development and persistence of personality in nature are counterintuitive because, in heterogeneous environments, personality is expected to limit the degree of behavioural flexibility. Recent work has shown that personality and behavioural flexibility might be linked, but their interaction is not well understood and could be elucidated by studying a… (More)
Personality in free-living individuals has predominantly been measured under standardized laboratory conditions. Such measurements have been then linked to life-history traits, fitness and survival. Yet, it remains unclear how such personality measurements reflect the variation shown by free-living individuals, if the same measurements were taken directly… (More)

This paper examines the application of a packet format that we introduce for Doppler scaling estimation in multicarrier signals. Both orthogonal frequency division multiplexing (OFDM) and filterbank multicarrier (FBMC) signals are examined in an at-sea experiment. We also investigate the use of non-uniform fast Fourier transform (NUFFT) for compensation of… (More)
