Jointly optimal chunk and power allocation in uplink SC-FDMA
(IEEE, 2013)For a single carrier frequency division multiple access (SC-FDMA) system, we obtain the jointly optimal power and chunk allocation policies which maximize the sum rate. Our solution is applicable to both localized and ... -
Low complexity least minimum symbol error rate based post-distortion for vehicular VLC
(Institute of Electrical and Electronics Engineers Inc., 2020-10-22)Vehicular visible light communications (VLC) has emerged as a viable supplement for high speed next-generation vehicle to vehicle (V2V) communication systems. However, performance of a V2V-VLC link is impaired due to ... -
Wavelet-based image compression by hierarchical quantization indexing
(IEEE, 2009)In this paper, we introduce the quantization index hierarchy, which is used for efficient coding of quantized wavelet coefficients. A hierarchical classification map is defined in each wavelet subband, which describes the ...
