Blind adaptive multiuser detection

IEEE Transactions on Information Theory, 1995
This paper introduces an adaptive multiuser detector which converges (for any initialization) to the minimum mean-square error detector without requiring training sequences. This blind multiuser detector requires no more knowledge than does the conventional single-user receiver: the desired user's signature waveform and its timing.

Multiuser Detection via Compressive Sensing

IEEE Communications Letters, 2012
In this paper, we consider a multiuser detection technique when the signal sparsity is changing over time. The key ingredient of our method is a clever switching between the CS reconstruction algorithm and classical detection depending on the sparsity level of the signals being detected. Since none of these approaches is uniformly better in a situation

Blind multiuser detection: a subspace approach

IEEE Transactions on Information Theory, 1998
Summary: A new multiuser detection scheme based on signal subspace estimation is proposed. It is shown that under this scheme, both the decorrelating detector and the linear minimum mean-square-error (MMSE) detector can be obtained blindly, i.e., they can be estimated from the received signal with the prior knowledge of only the signature waveform and ...

Blind adaptive multiuser detection

GLOBECOM '05. IEEE Global Telecommunications Conference, 2005., 2005
We propose a new blind multiuser signal model and detection framework for solving the near-far problem in synchronous CDMA in this paper. Compared with existing blind detectors, the proposed framework requires a minimum number of previously received signals, which is about the number of interfering users, and no sub-space separation or sequence ...

Multistage multiuser detection for FHMA

IEEE Transactions on Communications, 2000
A multistage multiuser detector (MMD) is presented for frequency-hopping/code-division multiple access (FH/CDMA.) The MMD reduces the bit-error rate (BER) over the conventional detector by exploiting prior knowledge of the addresses and energies of the user signals. This detector is a conservative multiuser detector which is robust to unknown users and

Multiuser detection of alamouti signals

IEEE Transactions on Communications, 2009
In a MIMO multiple-access channel where users employ Space-Time Block Codes (STBC), interference cancellation can be used to suppress co-channel interference and recover the desired signal of each user at the receiver. Leveraging the special properties of Alamouti matrices, we first show that spatial multiplexing of Alamouti signals retains the space ...
