Abstract— The inherent spread spectrum nature in ultrawideband (UWB) communications can support simultaneous transmissions. Two nearby transmissions do not collide, but rather ge...
The IEEE 802.11 standard currently does not offer support to exploit the unequal perceptual importance of multimedia bitstreams. All packets affected by channel errors, in fact, ...
We consider the uplink of two mobile stations with the help of one common relay. Recently, joint network-channel coding based on LDPC codes was proposed for this setup where the ch...
