In this letter, we propose an efficient signal detection method for uplink multiuser systems based on collaborative spatial multiplexing (CSM). The proposed method achieves near-optimal performance and shows only 0.8dB loss at the target frame error rate (FER) of 10-2. Moreover, the error performance of each user is almost the same in the proposed method, which is an important property in a multiuser MIMO system where each user's error performance must satisfy some fixed error rate criteria.
