A Gradient Based Peak-to-Average Power Ratio Reduction Method

Autor: Alex Grant, J. Baliga, Graeme Woodward, A.P. Kind

Publikováno v: GLOBECOM

One promising approach to peak to average power ratio (PAPR) reduction for orthogonal frequency division multiple access (OFDMA) is the use of reserved tones, which are modulated so as to reduce the PAPR. One problem with this approach is the computa

A Scalable 7.2 Mb/s 3GPP HSDPA Co-processor with Advanced NLMS Receiver and Receive Diversity for Mobile Terminals

Publikováno v: CICC

An HSDPA co-processor for 3G mobile terminals performs all layer 1 baseband chip rate, symbol rate, physical channel and transport channel processing required to receive 3GPP Release 6 HSDPA at data rates up to 7.2 Mb/s. The design is scalable to all

Iterative Decoding of Overloaded Multi-access Systems

Autor: A.P. Kind

Publikováno v: 2005 Australian Communications Theory Workshop.

Multiuser detection and decoding is generally more difficult when the channel is singular, which is always the case when the number of users exceeds the number of receiver observations. In this work we propose an iterative receiver that explicitly ex

A tree search method for iterative decoding of underdetermined multiuser systems

Autor: A.P. Kind, Alex Grant

Publikováno v: ISIT

Application of the turbo principle to multiuser decoding results in an exchange of probability distributions between two sets of constraints. Firstly, constraints imposed by the multiple-access channel, and secondly, individual constraints imposed by

Very-high rate space-time coding

Autor: Alex Grant, A.P. Kind

Publikováno v: ITW

A space-time coding method with low decoding complexity suitable for large numbers of antennas and high data rates is presented. High dimensionality is accommodated through use of a sub-optimal receiver that efficiently locates short vectors in a hig

Low complexity list detection for high-rate multiple-antenna channels

Autor: A.B. Reid, Alex Grant, A.P. Kind

Publikováno v: IEEE International Symposium on Information Theory, 2003. Proceedings..

We propose a low-complexity method approximating a-posteriori probability calculation for high-dimensional multiple-antenna systems. The pro- posed method out-performs sphere-decoder based ap- proaches, yet requires lower complexity. I. SYSTEM MODEL

On estimating the symbol APP in MIMO systems

Autor: A.P. Kind, Alex Grant

Publikováno v: Scopus-Elsevier
ISIT

A strategy is described for closely approximating the symbol a-posteriori probabilities in systems with large dimensionality, by marginalising over a small high-probability subset of possible sequences. The variation in the required size of this subs
