Automatic modulation classification for mimo systems using fourth-order cumulants
(IEEE, 2012)Automatic classification of the modulation type of an unknown communication signal is a challenging task, with applications in both commercial and military contexts, such as spectrum surveillance, cognitive radio, and ... -
Channel estimation for space-time block coded OFDM systems in the presence of multipath fading
(IEEE, 2002)In this paper, a computationally efficient, non-data-aided maximum a posterlori(MAP) channel estimation algorithm is proposed for orthogonal frequency division multiplexing (OFDM) systems with transmitter diversity using ... -
Generic BER analysis of VLC channels impaired by 3D user-mobility and imperfect CSI
(Institute of Electrical and Electronics Engineers Inc., 2021-07)Visible light communications (VLC) has emerged as a high-speed, low-cost, and green supplement for the existing radio frequency (RF) based infrastructures. However, the performance of VLC based systems is found to degrade ... -
Power control in the cognitive cooperative multiple access channel
(IEEE, 2012)We extend several encoding and decoding techniques from cooperative communications framework, to a cognitive radio system consisting of a primary user (PU) and a secondary user (SU), sending their messages to a common ... -
Window and backwards decoding achieve the same sum rate for the fading cooperative Gaussian multiple access channel
(IEEE, 2006)For a two user fading Gaussian multiple access channel with user cooperation, we show that window decoding achieves the same sum rate as backwards decoding, when the encoding is done using block Markov superposition coding. ...
