Intelligent Diagnosis of Urban Underground Drainage Network: From Detection to Evaluation
Structural Control and Health Monitoring, Volume 2024, Issue 1, 2024.During the process of urban development, there is large‐scale laying of underground pipeline networks and coordinated operation of both new and old networks. The underground concrete drainage pipes have become a focus of operation and maintenance due to their strong concealment and serious corrosion.

Uplink Channel Estimation for Bandlimited MC-DS-CDMA Systems Relying on Long Spreading Codes [PDF]
, 2011 This paper considers pilot-based parameter estimation for bandlimited MC-DS-CDMA systems relying on long spreading codes. Three different schemes are proposed and compared. The two so-called unstructured algorithms, namely the Least Squares Estimator (LS-

International Journal of Antennas and Propagation, 2011 The aim of this paper is to combine smart antenna beamforming and RAKE receiver in wideband code division multiple access (WCDMA). The proposed method combines spatial diversity as well as temporal diversity to improve the performance and overcome both ...

A Subspace Approach to Blind Multiuser Detection for Ultra-Wideband Communication Systems
EURASIP Journal on Advances in Signal Processing, 2005 Impulse radio-based ultra-wideband (UWB) communication systems allow multiple users to access channels simultaneously by assigning unique time-hopping codes to individual users, while each user's information stream is modulated by pulse-position ...
