Successive interference cancellation with SISO decoding and EM channel estimation Academic Article uri icon

abstract

  • We derive a low-complexity receiver scheme for joint multiuser decoding and parameter estimation of code division multiple access signals. The resulting receiver processes the users serially and iteratively, and makes use of soft-in soft-out single-user decoders, of soft interference cancellation and of expectation-maximization parameter estimation as the main building blocks. Computer simulations show that the proposed receiver a achieves near single-user performance at very high channel load (number of users per chip) and outperforms conventional schemes with similar complexity.
