Sequential Least Squares Algorithms for Blind Co-channel Signal Separation
نویسندگان
چکیده
In this paper we consider a problem of blind co-channel signal separation, the goal of which is to estimate multiple co-channel digitally modulated signals using an antenna array. We consider the joint maximum likelihood estimation [1] and present a sequential algorithm, which is referred to as sequential joint maximum likelihood (SJML) algorithm. In addition we also apply the sequential least squares to ILSP [2] and the resulting algorithm is referred to as the sequential least squares with projection (SLSP). Useful behavior of these two algorithms are confirmed by simulations.

Performance Analysis of Blind Digital Signal
We have recently proposed a blind approach for separating multiple co-channel digital signals received at an antenna array. This approach exploits the nite alphabet property of digital signals to simultaneously estimate the array response and symbol sequence for each signal. In 1, 2], we presented two eecient algorithms for computing the estimates: Iterative Least-Squares with Projection (ILSP)...
متن کاملBlind source separation using least-squares type adaptive algorithms
In this paper adaptive least-squares type algorithms are introduced for blind source separation. They are based on minimizing a criterion used in context with nonlinear PCA (Principal Component Analysis) networks. The new algorithms converge clearly faster and provide more accurate results than typical current adaptive blind separation algorithms based on instantaneous gradients. They are also ...
متن کاملBlind source separation of instantaneous MIMO systems based on the least-squares Constant Modulus Algorithm
Blind symbol detection for mobile communications systems has been widely studied and can be implemented by using either adaptive or iterative techniques. However, adaptive blind algorithms require data of sufficient length to converge. Therefore, in a rapidly changing environment, they are likely unable to track the changing channels. In such a situation, one possible solution is to use iterati...
متن کاملSemi-blind separation and detection of co-channel signals
We propose a semi-blind algorithm for smart antennas that, in addition to some structural signal properties, utilises user identifiers that are available in existing cellular systems. Our algorithm estimates, first, the row span of the adequately composed data matrix and then projects the obtained basis vectors iteratively to the finite alphabet (FA) constellation. We call the projection part o...
متن کاملBlind digital signal separation using successive interference cancellation iterative least squares
Blind separation of instantaneous linear mixtures of digital signals is a basic problem in communications. When little or nothing can be assumed about the mixing matrix, signal separation may be achieved by exploiting structural properties of the transmitted signals, e.g., finite alphabet or coding constraints. We propose a monotonically convergent and computationally efficient iterative least ...
