DCT-based phase correlation motion estimation
A DCT-based phase correlation motion estimation algorithm is proposed in this paper. By combining four real transforms, a new complex linear phase transform is obtained and is use...

Factor graph based design of an OFDM-IDMA receiver performing joint data detection, channel estimation, and channel length selec
We present a factor graph based design of a receiver for pilotassisted OFDM-IDMA systems transmitting over frequency-selective channels. The receiver performs joint iterative mult...

A factor graph approach to joint iterative data detection and channel estimation in pilot-assisted IDMA transmissions
We consider a pilot-assisted interleave-division multiple access (IDMA) system transmitting over block-fading channels. We describe this system in terms of a factor graph and use ...
