In this paper, we propose a modified maximum likelihood (ML) decision for a relay-based cooperative communication system using complex field network coding (CFNC). Since the traditional uncoded relay network which is wirelessly connected by inband wi

In this paper, we propose a fast AGC (Automatic Gain Control) scheme for 3GPP (3rd Generation Partnership Project) LTE (Long Term Evolution) TDD (Time Division Duplex) system. Since the received signal has a large signal power difference between upli

To mitigate the asynchronous ICI (Inter-Cell Interference), the CFR (Channel Frequency Response) and SCM (Spatial Covariance Matrix) should be accurately estimated. Therefore, the enhanced asynchronous ICI mitigation scheme which can effectively redu

In this paper, an efficient inter carrier interference (ICI) cancellation method for cooperative space time block coded orthogonal frequency division multiplexing (STBC-OFDM) system is presented. In cooperative STBC-OFDM system, ICI cancellation is n

For OFDM systems with multiple transmit antennas, it is necessary to obtain a reliable CFR of each transmitted signal from the received signal which is the superposition of transmitted signals. Generally, pilot symbol aided frame structure is used fo

To mitigate the asynchronous ICI (inter-cell interference), SCM (spatial covariance matrix) of the asynchronous ICI plus background noise should be accurately estimated for MIMO-OFDMA (multiple-input multiple-output-orthogonal frequency division mult

To mitigate the asynchronous ICI (Inter-Cell Interference), the CFR (Channel Frequency Response) and SCM (Spatial Covariance Matrix) should be accurately estimated. Therefore, we propose the ML (Maximum Likelihood)-based iterative method which can ef

An enhanced discrete Fourier transform (DFT)-based channel estimation for OFDM system is proposed. Conventional DFT-based channel estimations improve the performance by suppressing time domain noise. However, the disadvantage is that the effect of no
