Adaptive multidimensional coded modulation over flat fading channels
We introduce a general adaptive coding scheme for Nakagami multipath fading channels. An instance of the coding scheme utilizes a set of 2 -dimensional (2 -D) trellis codes origina...

Spectral efficient transmit diversity techniques without cyclic prefix for fading relay channels
Abstract--This paper proposes spectral efficient relayassisted transmit diversity techniques, i.e., space-time and space-frequency block codes (STBC/SFBC), for single carrier frequ...

Iterative frequency domain channel estimation for dft-precoded ofdm systems using in-band pilots
We consider two techniques of in-band frequency domain multiplexed (FDM) pilots using interleaved frequency domain multiple access (IFDMA) signal with a Chu sequence for DFT-precod...

A spectral approach to recursive end-to-end distortion estimation for sub-pixel motion-compensated video coding
Error resilient video coding critically relies on the accuracy of endto-end distortion estimation. An established solution, the recursive optimal per-pixel estimate (ROPE), is bas...
