Improved detection in CDMA for biased sources
2007
Journal of Physics A: Mathematical and Theoretical
We consider the detection of biased information sources in the ubiquitous Code-Division Multiple-Access (CDMA) scheme. We propose a simple modification to both the popular single-user matchedfilter detector and a recently introduced near-optimal message-passing based multiuser detector. This modification allows for detecting modulated biased sources directly, with no need for source coding. Analytical results and simulations with excellent agreement are provided, demonstrating substantial
