Training Over Sparse Multipath Channels in the Low SNR Regime
Elchanan Zwecher, Dana Porrat
Training over sparse multipath channels is explored. The energy allocation and the optimal shape of training signals that enable error free communications over unknown channels are…
Spreading Signals in the Wideband Limit
Elchanan Zwecher, Dana Porrat
Wideband communications are impossible with signals that are spread over a very large band and are transmitted over multipath channels unknown ahead of time. This work exploits the…
Channel Uncertainty in Ultra Wideband Communication Systems
Dana Porrat, David N. C. Tse, Serban Nacu
Wide band systems operating over multipath channels may spread their power over bandwidth if they use duty cycle. Channel uncertainty limits the achievable data rates of power cons…
Performance of PPM Multipath Synchronization in the Limit of Large Bandwidth
Dana Porrat, Urbashi Mitra
The acquisition, or synchronization, of the multipath profile for an ultrawideband pulse position modulation (PPM) communication systems is considered. Synchronization is critical…
