Summary: 
A unified linear multiuser receiver that minimizes a weighted sum of the multiple access interference (MAI) and the background noise is introduced. The proposed receiver includes the three popular linear receivers, namely the matched-filter, the decorrelating and the minimum mean-square-error receivers as special cases. Furthermore, by tuning a single weighting factor, it is possible to improve the performance of the proposed receiver over that of any of the above mentioned linear receivers.
