We investigate the use of discrete-time analog joint source channel coding (JSCC) in a wireless sensor network where the source of information is wirelessly powered by the destination. Wireless energy transfer and information transmission are multiplexed via a time-switching protocol. As a fraction of the time slot is spent for energy transfer, the source samples are saved and compressed using either...
We investigate the performance of bandwidth expansion analog joint source-channel coding (JSCC) over fading channels. Non-linear spiral-like curves and maximum likelihood detector with linear minimum mean square error estimator are considered. Under Rayleigh fading this scheme presents a gap to the theoretical limit which increases with the channel signal to noise ratio (CSNR), while the same scheme...
