In this paper, we assessed feasibility of using Photoplethysmography (PPG) signal from flexible biosensor as an alternative solution to ECG for monitoring of cardiovascular and pulmonary performance. The potential advantage of this methodology is reduction in power consumption and improvement of complexity of body worn wireless multisensory platform for(More)
In this paper, a transmission of JPEG2000 images using an Unequal Power Allocation (UPA) scheme and Orthogonal Frequency Division Multiplexing (OFDM) technique over a block fading - frequency selective channel is presented. Using instantaneous and average channel state information, power is assigned to each bit in the JPEG2000 bitstream based on its(More)
In this paper, an adaptive scheme is developed for an Unequal Power Allocation (UPA) algorithm in a way to allow variable size grouping of the coding passes to enhance the optimization process at different Signal to Noise Ratio (SNR) values. The optimization algorithm exploits the hierarchical structure of the JPEG2000 images and uses a distortion model(More)
