Crosstalk is a major factor in inducing performance degradation of the next generation very-high bit-rate digital subscriber line (VDSL) system. Many crosstalk cancellation methods such as Zero-forcing (ZF) algorithm, First-Order (FO) algorithm, iterative crosstalk cancellation algorithm etc. have been proposed. These methods are based on the assumption that the number of users and the crosstalk environment...
A blind signal-to-interference-plus-noise ratio (SINR) estimation method is proposed for orthogonal frequency division multiplexing (OFDM) systems in the presence of impulsive noise over multi-path fading channels. By exploiting the cyclostationarity of the OFDM signal, the received signal power is decomposed into the transmitted signal power and the impulsive interference plus the Gaussian noise...
This paper deals with the problem of blind signal to noise ratio (SNR) estimation for MIMO-OFDM system. Existing MIMO-OFDM SNR estimators are based on the knowledge of pilot sequences which is not applicable in some environment. A novel blind SNR estimation algorithm for MIMO-OFDM system is proposed. In this algorithm, we first select appropriate Cyclic postfix length of the transmitter signal to...
