A Survey on MMSE Detector Using Space Time Diversity Technique

چکیده
In this paper, we present the survey on MMSE Detector using space time diversity technique. The fulldiversity spacefrequency block codes (SFBCs) focused around orthogonal space-time block codes (OSTBCs). We studied that the Space Time Diversity Technique is fit for achieving full-differing qualities and rate-one attributes for two transmit reception apparatuses, despite the fact that the evidence of full-differences property is restricted to the genuine star groupings. Likewise for the QPSK star grouping, as of late proposed full-differences space-timefrequency block codes (STFBCs) by and large experience the ill effects of high computational many-sided quality at the receiver side.

Near-far resistance of Alamouti space-time coded CDMA communication systems
In this paper, the neax-far resistance of the MMSE detector is derived for the code division multiple access (CDMA) communication systems with the Alamouti space-time block coding. It is shown that transmitter/receiver diversity has benefits on the near-far resistance performance while receiver diversity has more impact on theTTear-far resistance.

n this work, decision feedback (DF) detection algorithms based on multiple processing branches for multi-input multi-output (MIMO) spatial multiplexing systems are proposed. The proposed detector employs multiple cancellation branches with receive filters that are obtained from a common matrix inverse and achieves a performance close to the maximum likelihood detector (MLD). Constrained minimum...

In this paper we propose a new space diversity scheme for broadband PLC systems using orthogonal space-time block coding (OSTBC) transmission combined with single-carrier frequency-domain equalization (SC-FDE). To apply this diversity technique to PLC channels, we first propose a new technique for combining SC-FDE with OSTBCs applicable to all dispersive multipath channels impaired by impulsive...

In this paper, we propose a multiuser detection (MUD) scheme for space-time block coded orthogonal frequency division multiplexing (STBC-OFDM) systems. We derive the optimum weight matrix used to decouple simultaneously signals from active multiple access users using the minimum mean square error (MMSE) multiuser detection method. The proposed scheme provides good performance over different mod...
متن کاملCovariance Analysis of a vector tracking GPS receiver based on MMSE multiuser Detection
In high dynamic conditions, using vector tracking loops instead of scalar tracking loops in GPS receivers is proved as an efficient method to compensate the performance. The Minimum Mean Squared Error detector as a multiuser detector is applied in the vector tracking loop for more reliability and efficiency. The Kalman filter does the two tasks of tracking and extracting the navigation data aft...
