Performance Analysis of a Simple Subspace Projection-Based Channel Estimate Improver for Multicarrier CDMA Systems

Autor: Fabian David Backx, Raimundo Sampaio-Neto, Deolinda Fontes Cardoso

Publikováno v: Journal of Communication and Information Systems. 28:14-25

This paper addresses pilot-assisted estimation offrequency-selective time-invariant channels in multicarrier Code Division Multiple Access communications systems (MC CDMA and MC DS-CDMA). Performance in terms of normalised mean square error (NMSE) is

Interpolation-and-decimation-based dimensionality reduction applied to space-time processing

Autor: Aline de Oliveira, Raimundo Sampaio-Neto, Fabian David Backx, José Mauro P. Fortes

Publikováno v: SAM

In this paper, we specialize a novel stage of dimensionality reduction, based on a joint interpolation and decimation scheme (JIDS), proposed in [1] and [2], for airborne phased-array radars. The JIDS design approach consists of a very elegant and ef

Performance of multicarrier CDMA systems with improved pilot-aided channel estimation

Autor: Raimundo Sampaio-Neto, Deolinda Fontes Cardoso, Fabian David Backx

Publikováno v: 2009 Sixth International Conference on Wireless On-Demand Network Systems and Services.

This research investigates a simple procedure to improve the channel frequency response estimate for orthogonal multicarrier CDMA systems. The improvement is achieved by means of a precomputed matrix that projects the original discrete frequency resp

Improved Pilot-Aided Channel Estimation in Zero Padded MC-CDMA Systems

Autor: Deolinda Fontes Cardoso, Raimundo Sampaio-Neto, Fabian David Backx

Publikováno v: 2009 4th International Symposium on Wireless Pervasive Computing.

This paper considers two simple procedures to improve the channel frequency response estimate for uplink Zero Padded MC-CDMA systems. The first approach uses a precomputed matrix that projects the original discrete frequency response onto the subspac
