Interior point least squares estimation: transient convergence analysis and application to MMSE decision-feedback equalization

Autor: Kon Max Wong, K.H. Afkhamie, Zhi-Quan Luo

Publikováno v: IEEE Transactions on Signal Processing. 49:1543-1555

In many communication systems, training sequences are used to help the receiver identify and/or equalize the channel. The amount of training data required depends on the convergence properties of the adaptive filtering algorithms used for equalizatio

Blind identification of FIR systems driven by Markov-like input signals

Autor: K.H. Afkhamie, Zhi-Quan Luo

Publikováno v: IEEE Transactions on Signal Processing. 48:1726-1736

We propose a new algorithm for the blind identification and equalization of finite impulse response (FIR) systems using the second-order statistics of the received signal. The new algorithm is set in the same context as the algorithms of Tong et al.

Adaptive linear filtering using interior point optimization techniques

Autor: K.H. Afkhamie, Zhi-Quan Luo, Kon Max Wong

Publikováno v: IEEE Transactions on Signal Processing. 48:1637-1648

We propose a novel approach for the linear adaptive filtering problem using techniques from interior point optimization. The main idea is to formulate a feasibility problem at each iteration and obtain as an estimate a filter near the center of the f

Characterization of in-home MIMO power line channels

Autor: Arun Nayagam, K.H. Afkhamie, D. Veronesi, Paola Bisaglia, Fabio Osnato, Deniz Rende, Lawrence W. Yonge, Raffaele Riva

Publikováno v: 2011 IEEE International Symposium on Power Line Communications and Its Applications.

In this paper a statistical description of in-home MIMO power line channels is derived, based on channel measurements in the 0 to 100 MHz range. In particular, it is shown that the power delay profile has a statistical distribution that could be well

Publikováno v: 2011 IEEE International Symposium on Power Line Communications and Its Applications.

In this paper we study the characteristics of in-home multi-input multi-output (MIMO) power line channels in the 0 – 100 MHz frequency band. Channel measurements are obtained in several US homes by transmitting two independent signals over two wire

Tradeoff between channel estimation accuracy and application throughput for in-home MIMO power line communication

Autor: Arun Nayagam, Srinivas Katar, K.H. Afkhamie, Deniz Rende, Lawrence W. Yonge

Publikováno v: 2011 IEEE International Symposium on Power Line Communications and Its Applications.

In this paper we consider two alternate packet structures for estimating the multi-input multi-output (MIMO) powerline channel and their impact on achievable application throughputs. In the first packet structure, an orthogonal pair of OFDM symbols i
