BLIND ADAPTIVE INTERFERENCE SUPPRESSION FOR DIRECT - SEQUENCECDMAJoaqu

چکیده
This paper deals with the problem of blind interference suppression in Direct-Sequence Code Division Multiple Access (DS/CDMA) channels. We investigate the incorporation of linear constraints to the Constant Modulus (CM) criterion to obtain a new blind adaptive receiver that only requires chip synchronization and acquisition of the desired user code. An analysis is presented that shows how linear constraints avoid the capture problem of the conventional CM criterion. Finally, an adaptive algorithm based on the Generalized Sidelobe Canceller 7] structure is proposed to solve the constrained optimization problem.

Enhanced Blind Adaptive Narrowband Interference Suppression in DSSS
This paper addresses blind adaptive suppression of a digital narrowband interferer in direct sequence spread spectrum (DSSS) communications.. We apply an adaptive suppression method for wideband interference proposed by Honig, Madhow and Verdd [1] to a narrowband interferer. We identify the eigenspaces of the system dynamics to: 1) significantly decrease convergence times via a new constraint o...
متن کاملLMMSE Receivers for DS-CDMA Systems in Frequency-Selective Fading Channels
| The linear minimum mean squared error (LMMSE) criterion can be used to obtain near-far resistant single-user receivers in direct-sequence code-division multiple-access (DS-CDMA) systems. The standard version (postcombining) of the LMMSE receiver minimizes the mean squared error (MSE) between the lter output and the actual transmitted data sequence. Since the detector depends on the channel co...
متن کاملBlind Demodulation of Direct-Sequence CDMA Signals Using an Antenna Array
Recent work on Direct-Sequence (DS) Code Division Multiple Access (CDMA) has shown that blind adaptive interference suppression techniques can be used for reliable demodulation, provided that the timing of the desired signal is known. The blind demodulator has since been used as a building block for a scheme for joint timing acquisition and demodulation. In this paper, we consider a blind adapt...

متن کاملBlind Adaptive Interference Suppression for the Near-Far Resistant Acquisition and Demodulation of D - Signal Processing, IEEE Transactions on
Two key operations required of a receiver in a direct-sequence (DS) code division multiple access (CDMA) system are the timing acquisition of transmissions that are starting up or have lost synchronization, and the demodulation of transmissions that have been acquired. The reliability of both these operations is limited by multiple-access interference, especially for conventional matched filter...
