FIR channel identification in multirate communication systems with a subspace method
نویسندگان
چکیده
The problem of blind channel identification for multirate, multi-user communication systems is addressed. By exploiting symbol rate differences, it is shown that users can .be separated based on the autocorrelation of the received signal, thus reducing the problem to the familiar single rate setting. A subspace method is then developed to identify the channel associated with each user. Simulations are used to explore algorithm performance as a function of key factors such as signal to noise ratio (SNR) and signal to interference ratio (SIR).

Statistical analysis of a subspace method for blind channel identification
This paper considers the problem of blind channel estimation of multi channel FIR lters. This is a problem arising in e.g. mobile communication systems using digital signalling. By using the orthogonality property between the noise subspace and the channel matrix, it has been shown in earlier work that the channel matrix is identiiable up to a multiplicative constant. In this article, the asymp...
متن کاملA frequency domain method for channel estimation in multirate communication systems
In this paper, a new frequency domain approach towarb blind channel identification for multirate communication systems is described. Users are first separated based on different cyclic frequencies corresponding to their respective symbol rates, thereby resulting in a single-user (blind) identification scenario. The algorithm proposed in [3] is then used to estimate the channels for each rate. C...
متن کاملNew precoding for intersymbol interference cancellation using nonmaximally decimated multirate filterbanks with ideal FIR equalizers
In this paper, we propose a new precoding method for intersymbol interference (ISI) cancellation by using nonmaximally decimated multirate filterbanks. Unlike the existing precoding methods, such as the TH and trellis precodings, the new precoding i) may be independent of the ISI channel; ii) is linear and does not have to implement any modulo operation; iii) gives the ideal FIR equalization at...
متن کاملMultiple Antenna System Equalization Using Semi-blind Subspace Identification Methods
In this paper, we investigate the application of the subspace system identification (SSI) method (e.g. N4SID) to the MIMO frequency-selective fading channel estimation problem. The FIR constraint on the MIMO channel model is suggested to be relieved to draw benefit from possible parsimonious parametrization of the MIMO channel when subchannels become correlated. Also, the criterion for training...
متن کاملBlind identification and order estimation of FIR communications channels using cyclic statistics
In this contribution we address the problem of the blind joint identification and order estimation of a non-minimum phase FIR communication channel by exploiting the cyclostationarity of the received signal sampled at rate greater of the symbol rate. We show that the identification can be formulated as a “subspace fitting” problem; this allows for using the subspace distance as a test statistic...
