Successive refinement via broadcast: Optimizing expected distortion of a Gaussian source over a Gaussian fading channel

Suhas Diggavi

We consider the problem of transmitting a Gaussian source on a slowly fading Gaussian channel, subject to the mean-squared error distortion measure. The channel state information is known only at the receiver but not at the transmitter. The source is assum ...

Embedded Rank Distance Codes for ISI channels

Suhas Diggavi, Sanket Dusad

Designs for transmit alphabet constrained space-time codes naturally lead to questions about the design of rank distance codes. Recently, diversity embedded multi-level space-time codes for flat fading channels have been designed from sets of binary matric ...

A real-time 4-stream MIMO-OFDM transceiver: System design, FPGA implementation, and characterization

Andreas Peter Burg

When designing complex communication systems, such as MIMO-OFDM transceivers, prototypes have become an important tool for understanding the implementation trade-offs and the system behavior. This paper presents a real-time FPGA prototype for a 4-stream MI ...

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 ...

A Leakage-Based Precoding Scheme for Downlink Multi-User MIMO Channels

Ali H. Sayed

In multiuser MIMO downlink communications, it is necessary to design precoding schemes that are able to suppress co-channel interference. This paper proposes designing precoders by maximizing the so-called signal-to-leakage-and-noise ratio (SLNR) for all u ...

On Successive Refinement of Diversity for fading ISI channels

Suhas Diggavi, Sanket Dusad

Abstract—Rate and diversity impose a fundamental tradeoff in communications. This tradeoff was investigated for IntersymbolInterference (ISI) channels in [4]. A different point of view was explored in [1] where high-rate codes were designed so that they ha ...

Adaptive Subchip Multipath Resolving for Wireless Location Systems

Ali H. Sayed

Reliable positioning of cellular users in a mobile environment requires accurate resolving of overlapping multipath components. However, this task is difficult due to fast channel fading conditions and data ill-conditioning, which limit the performance of ...
