Standard face recognition algorithms that use standard feature extraction techniques always suffer from image performance degradation. Recently, singular value decomposition and low-rank matrix are applied in many applications,including pattern recognition and feature extraction. The main objective of this research is to design an efficient face recognition approach by combining many tech...

In this work, we focus on the model-mismatch problem for model-based subspace channel tracking in correlated underwater acoustic channel. A model based channel's correlation can be used as state-space Kalman filter to improve compared that without a model. Even though data support assumption is slow-varying and uncorrelated some degree, performance further, not ignore because most models encoun...

Snowflake Vitreoretinal Degeneration (SVD) is associated with the R162W mutation of the Kir7.1 inwardly-rectifying potassium channel. Kir7.1 is found at the apical membrane of Retinal Pigment Epithelial (RPE) cells, adjacent to the photoreceptor neurons. The SVD phenotype ranges from RPE degeneration to an abnormal b-wave to a liquid vitreous. We sought to determine how this mutation alters the...

This paper presents a new 3-D subband coding framework that is able to achieve a good balance between high compression performance and channel error resilience. Various data transform methods for the decorrelation of video were examined and compared, including subband filtering, discrete cosine transforms, discrete wavelet transforms, and lapped transforms. The coding stage of the algorithm is ...

In this paper, an efficient and fair algorithm for resource management in MIMO-OFDM systems is proposed. The system used for this analysis is the downlink of multi-user MIMO-OFDM system. Based on channel state information (CSI), the base station (BS) employs singular value decomposition (SVD) to transmit the MIMO channel into parallel subchannels for each subcarrier, and then subcarriers, are a...

The accurate location of an unknown radio emitter (URE) is a critical task in wireless communication security. URE localization method based on the received signal strength difference (RSSD) has become popular due to identification transmitting power and frequency. However, high computational complexity low positioning accuracy have been caused by RSSD fingerprint data’s redundancy cross-correl...

A fundamental problem in adaptive sensor array processing is to identify unknown uncorrelated colored signals that are distorted by unknown convolutive channels. This problem is also known as blind identification of MIMO (multi-input-multioutput) systems. In this paper, we present a novel approach called BIDS (blind identification by decorrelating subchannels). The BIDS can identify an FIR (fin...

In multiple-input multiple-output (MIMO) systems, precoders design pose significant implementation challenges due to the high computational complexity of the singular value decomposition (SVD) of the channel matrix. In this paper, we use the iterative COordinate Rotation DIgital Computer (CORDIC) algorithm to compute the SVD for different configurations of multi-antenna systems. The complexity/...

This paper presents a new joint channel estimation method for Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) systems based on a Singular Value Decomposition (SVD) reduced-rank technique. The system capacity is increased by increasing the highest number of users in one time slot. The additional channel estimation processing required for the increasing number of users is solve...

Mathematical expressions for the interferometric coherence of homogeneous-volume-over-ground models (RVoG and OVoG) for the case of dominant specular scattering and considering a single-tx interferometer are derived. The analysis of the positions of the coherences on the complex plane, as a function of the polarization channel, yields important differences for the single-tx and the alternate-tx...
