Robust transmit processing for frequency-selective fading channels with imperfect channel feedback
Reliable channel state information at the transmitter (CSIT) can improve the throughput of wireless networks significantly. In a realistic scenario, there is a mismatch between th...

Limited feedback achieves the empirical capacity
The utility of limited feedback for coding over an individual sequence of DMCs is investigated. This study complements recent results showing how limited or noisy feedback can boo...

How to beat the sphere-packing bound with feedback
The sphere-packing bound Esp(R) bounds the reliability function for fixed-length block-codes. For symmetric channels, it remains a valid bound even when strictly causal noiseless ...

Energy efficient lossy transmission over sensor networks with feedback
The energy-distortion function (E(D)) for a network is defined as the minimum total energy required to achieve a target distortion D at the receiver without putting any restricti...

Progressive Image Transmission over OFDM Systems using Multiple Antennas
A Joint source-channel coding (JSCC) scheme for SPIHT coded image transmission over OFDM systems with spatial diversity is proposed where no feedback channel is available. By usin...
