Training-based channel estimation and de-noising for the UMTS TDD mode
نویسندگان
چکیده
In this paper we provide a theoretical framework of de-noising for UMTS TDD-like mobile radio communication systems. Based on the Bayesian approach, we show how to denoise channel estimates provided by the Training-based estimation procedure. The proposed schemes allow not only for eliminating major drawbacks of hard thresholding but also for a low complexity implementation.

Channel Estimation Method with Improved Performance for the UMTS-TDD Mode
2 Universidade de Aveiro, Instituto de Telecomunicações / DETUA, 3810 Aveiro, Portugal Abstract Channel estimation is an essential building block for UTRA-TDD high performance receivers. Once the performance of the channel estimator algorithm proposed by 3GPP is highly dependent on the time spreading between consecutive multi-path components, a Successive Multi-path channel Estimation Technique...
متن کاملConcatenated extended complementary sequences for inter-base station synchronization in UMTS TDD mode
This paper presents a new family of synchronisation sequences, Concatenated Extended Complementary (CEC) sequences. CEC-sequences have recently been adopted for Release 4 of UMTS TDD mode as inter-base station synchronisation codes. They provide perfect auto-correlation properties within a windo of adjustable size, excellent overall auto-correlation properties and allow the use of low-complexit...
متن کاملSpace-time algorithms for multiuser channel estimation in the downlink of UMTS/TDD
We present space-time methods for channel estimation in the downlink of a UMTS/TDD system. The channels associated to all base stations near the mobile receiver are estimated by a multiuser, multi-antenna technique. We develop a minimum mean-square error (MMSE) channel estimator that incorporates midamble detection/estimation and least-squares channel estimation as preparatory stages. Combinati...
متن کاملSpatial and Space-Time Algorithms for Synchronisation in the Downlink of the UMTS FDD and TDD Modes
This paper presents methods for synchronisation in the downlink of the FDD and TDD modes of a UMTS system. Space-time processing based on multiple receive antennas is used to suppress co-channel interference caused by other base stations. We develop a detection-based synchronisation procedure exploiting the structure of the respective UMTS mode, for which we present two alternative detection al...
متن کاملA semi-blind channel estimation technique based on second-order blind method for CDMA systems
This paper aims at studying a semi-blind channel estimation scheme based on the subspace method or a carefully weighted linear prediction approach. The corresponding (composite) semi-blind cost functions result from a linear combination of the training-based cost function and a blind cost function. For each blind method, we show how to calculate the asymptotic estimation error. Therefore, by mi...
