A Linear Receiver for Coded Multiuser CDMA - Alexander, Rasmussen, Schlegel (1997) (Correct)
....complex. Also the theoretical degradation relative to the single user bound is derived. Keywords CDMA, random codes, convolutional codes I. Introduction The majority of research on receivers for CDMA communications systems has been in the area of uncoded receiver design [1] 2] 3] [4], 5] Once the multiuser interference (MUI) has been resolved, error control coding can be applied independently. In this case hard decisions on the coded bits of each user are made prior to decoding. Clearly, this segmented design philosophy is suboptimal since we are throwing away information ....

On Improved Multiuser Detection With Iterated Soft Decision.. - Lampe, Huber (1999) (1 citation) (Correct)
.... of the users transmitted data symbols has been described by Verd u [1] Since this receiver is too complex, numerous suboptimum linear receivers with and without feedback have been proposed (see [2, 3, 5] Additional performance gains are achievable with iterated decisionfeedback schemes (see [6]) The main idea of these receiver concepts is to increase the reliability of the decision on a user s data symbol by using estimates obtained for other users symbols in order to cancel their interference. Here, the feedback of soft instead of hard decisions is highly preferable (see [7, 8] ....

....is applied in a 22 decorrelator which eliminates MAI (where R is obtained from the channel estimation process) So b d decorr = R ;1 y = Ad R ;1 : 3.4) 3. Differencing Multistage: This is an efficient version of multistage detectors which uses a parallel interference cancellation technique [20]. Here the detector estimates and cancels the interference MAI for each user in parallel. This method removes the necessity to calculate the inverse of R, by using an iterative method to successively cancel the interference. In multistage detection, the l th stage of the detection is b z (l) ....

....accurate detection. 2. 4 Multiuser Detection Multiuser detection tries to cancel the interference from other users to improve the error rate performance, as opposed to single user detection using a matched filter [12] The detection scheme discussed is the Differencing Multistage detection method [15, 17], which is based on the principle of Parallel Interference Cancellation. The channel estimate matrix can be fed directly into the multistage detector. Dropping the subscript i for convenience, the matrix A i can be rearranged into its odd and even columns A 0 # A 1 2 C K ThetaN which ....
