Optimal Tone Reservation for Peak to Average Power Control of CDMA Systems


In this paper we study the tone reservation technique for the reduction of the peak to average power ratio (PAPR) in code division multiple access (CDMA) systems that employ the Walsh functions. In the tone reservation method, the available carriers are partitioned into two sets, the information set, which carries the information, and the compensation set, which is used to reduce the PAPR. Central questions are: What is the best possible reduction of the PAPR? What is the optimal information set that achieves this reduction, and how can it be found?

Tone Reservation and Solvability Concepts for the PAPR Problem in General Orthonormal Transmission Systems


Large peak to average power ratios (PAPRs) are problematic for communication systems. One possible approach to control the PAPR is the tone reservation method. We analyze the tone reservation method for general complete orthonormal systems, and consider two solvability concepts: strong solvability and weak solvability. Strong solvability requires a rather strong control of the peak value of the transmit signal by the energy of the information signal, and thus might be to restrictive for practical applications.

COMPLEXITY REDUCTION OF EIGENVALUE DECOMPOSITION-BASED DIFFUSE POWER SPECTRAL DENSITY ESTIMATORS USING THE POWER METHOD


In noisy and reverberant environments speech enhancement techniques such as the multi-channel Wiener filter (MWF) can be used to improve speech quality and intelligibility. Assuming that reverberation and ambient noise can be modeled as diffuse sound fields, such techniques require an estimate of the diffuse power spectral density (PSD). Recently a multi-channel diffuse PSD estimator based on the eigenvalue decomposition (EVD) of the prewhitened signal PSD matrix was proposed.

Interfeference Alignment on MIMO X channel with Synergistic CSIT


The achievable degree of freedom (DoF) boosting has been
demonstrated on a single-input single-output (SISO) X channel
by using outdated and instantaneous channel state information
at transmitter (CSIT) synergistically, in contrast to
that of using completely outdated CSIT. However, the means
by which the DoF gain can be obtained in a multiple-input
multiple-output (MIMO) system remains unclear. This paper
proposes an interference alignment scheme with synergistic
CSIT for MIMO X channel. We show that the achievable

A JOINT DESIGN APPROACH FOR SPECTRUM SHARING BETWEEN RADAR AND COMMUNICATION SYSTEMS


Diagram for Coexisting Radar and Communication Systems

A joint design approach is proposed for spectrum sharing between MIMO radar and MIMO communication systems. Radar transmit precoding and adaptive communication transmission are adopted, and are jointly designed to maximize signal-to-interference-plus-noise ratio (SINR) at the radar receiver subject to the communication system meeting certain rate and power constraints. We start with the design of a system in which knowledge of the target information is used. Such design can be used to benchmark the performance of schemes that do not use target information.

Radar Precoding for Spectrum Sharing Between Matrix Completion Based MIMO Radars and A MIMO Communication System


The paper investigates a new framework for spectrum sharing between a MIMO-MC radar (MIMO radar using matrix completion) and a MIMO communication system, based on radar transmit precoding. The radar transmit precoder is jointly designed with the communication codewords so that the SINR at the radar receiver is maximized while meeting certain rate and power constraints at the communication system. By shaping the transmit beam, the proposed approach results in enhanced SINR at the receive antennas.
