Capacity of Sparse Wideband Channels with Partial Channel Feedback
Gautham Hariharan, Vasanthan Raghavan, Akbar M. Sayeed
This paper studies the ergodic capacity of wideband multipath channels with limited feedback. Our work builds on recent results that have established the possibility of significant…
Non-Coherent Capacity and Reliability of Sparse Multipath Channels in the Wideband Regime
Gautham Hariharan, Akbar Sayeed
In contrast to the prevalent assumption of rich multipath in information theoretic analysis of wireless channels, physical channels exhibit sparse multipath, especially at large ba…
Capacity of Sparse Multipath Channels in the Ultra-Wideband Regime
Vasanthan Raghavan, Gautham Hariharan, Akbar Sayeed
This paper studies the ergodic capacity of time- and frequency-selective multipath fading channels in the ultrawideband (UWB) regime when training signals are used for channel esti…
