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 ...

Reducing Buffer Space in Multipath Schemes

Maysam Yabandeh, Sajjad Zarifzadeh

One major drawback of multipath transferring schemes, which is inspired by the usage of different paths with diverse delays, is the emergence of reordering among packets of a flow. This reordering brings some substantial problems (like larger delay and buf ...

Achievable Rates for Conferencing Multiway Channels

Michael Christoph Gastpar

A generalization of the additive Gaussian two-way channel to M users is considered. Such channels contain implicit feedback in the sense that the channel output signals observed by the different encoders are correlated. While the benefits of feedback are s ...

On the Joint Compensation of IQ Imbalances and Phase Noise in MIMO-OFDM Systems

Ali H. Sayed

OFDM systems are susceptible to receiver impairments such as IQ imbalance and phase noise. These impairments can severely degrade the achievable effective signal-to-noise ratio at the receiver. In this paper, we propose a joint compensation scheme to mitig ...

Compensation of Phase Noise in OFDM Wireless Systems

Ali H. Sayed

Phase noise causes significant degradation in the performance of orthogonal frequency division multiplexing (OFDM)-based wireless communication systems. The presence of phase noise can reduce the effective signal-to-noise ratio (SNR) at the receiver, and c ...

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 ...

Performance of an Impulse Radio Communication System in the Presence of Gaussian Jitter

Pierre-André Farine, Cyril Botteron

In this paper, the bit error rate (BER) performance for an ultra-wide bandwidth (UWB) impulse radio in an additive white Gaussian noise (AWGN) transmission channel and with Gaussian jitter is estimated. The assumed receiver combines the received pulses to ...

Diversity-Multiplexing-Delay Tradeoff in Half-Duplex ARQ Relay Channels

Sanket Dusad

In this paper, we present an efficient protocol for the delay-limited fading ARQ single relay half duplex channel. The source is using an ARQ retransmission protocol to send data to the relay and the destination. When the relay is able to decode, both 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 ...

Joint Compensation of IQ Imbalance and Phase Noise in OFDM Systems

Ali H. Sayed

The joint effects of IQ imbalance and phase noise on OFDM systems are analyzed, and a compensation scheme is proposed to improve the system performance. The scheme consists of a joint channel estimation algorithm and a joint data symbol estimation algorith ...
