Achieving Linear Scaling with Interference Alignment

Ayfer Özgür Aydin

Recent results have shown that interference alignment can achieve K/2 degrees of freedom in a K-user interference channel with time or frequency varying channel coefficients. For fixed number of users K, the number of degrees of freedom characterizes the a ...

Successive cancellation for cyclic interference channels

Eren Sasoglu

The Chong-Motani-Garg inner bound for the two-user interference channel is generalized to a special case of many-user interference channels. By taking a geometric viewpoint and using rate-splitting arguments, it is shown that all operating points in the Ch ...

On the Use of Cascade Structure to Correct Impulsive Noise in Multicarrier Systems

We propose a new decoding algorithm based on a cascade structure for impulsive noise correction in multicarrier systems such as Orthogonal Frequency Division Multiplexing (OFDM) based systems. This new cascade structure based algorithm has the advantage to ...

An Efficient Carrier Phase Synchronization Technique for High-Order M-QAM–OFDM

Ali H. Sayed

In this correspondence, we propose a blind carrier phase synchronization algorithm for high-order M-ary quadrature amplitude modulation-orthogonal frequency division multiplexing (M-QAM-OFDM) systems, which can effectively recover residual frequency offset ...

Successive refinement of ISI channels with single degree of freedom

Suhas Diggavi, Sanket Dusad

Rate and diversity impose a fundamental trade-off in communications. This tradeoff was investigated for Intersymbol Interference (ISI) channels in [7]. A different point of view was explored in [4] where high-rate codes were designed so that they have a hi ...

OFDM Channel Estimation in the Presence of Frequency Offset, IQ Imbalance and Phase Noise

Ali H. Sayed

OFDM systems are susceptible to receiver impairments like frequency offset, IQ imbalance and phase noise. In this paper, OFDM channel estimation in the presence of these impairments is studied, and an iterative algorithm is proposed to jointly estimate the ...

FFT processor for OFDM channel estimation

Andreas Peter Burg

Pilot-assisted channel estimation for communication systems employing orthogonal frequency division multiplexing modulation requires significant signal processing at the receiver if the correlation among the frequency-domain channel coefficients is to be e ...
