Delay and DOA estimation in CDMA communication systems via maximum likelihood techniques
We present a maximum likelihood method for delay estimation in a CDMA wireless communication system. An antenna array is used at the receiver, which facilitates the concomitant estimation of the direction of arrival (DOA) ...
VLSI implementation of the multistage detector for next generation wideband CDMA receivers
(Kluwer Academic Publishers, 2002-03-20)
The multistage detection algorithm has been proposed as an effective interference cancellation scheme for next generation Wideband Code Division Multiple Access (W-CDMA) base stations. In this paper, we propose a real-time ...
Computationally Efficient Multiuser Detectors
CDMA is becoming an increasingly popular multiplexing scheme in wireless communications and this has necessitated the development of efficient detection techniques. The exponential complexity of the optimal detector on ...
Spreading and Power Allocation for Multiple Antenna Transmission using Decorrelating receivers
We propose a new scheme for multiple antenna transmission in the context of spread spectrum signaling. The new scheme consists of using shifted Gold sequences to modulate independent information on the multiple antennas. ...
On Multipath Channel Estimation for CDMA Systems Using Multiple Sensors
This paper focuses on the design of a multiuser receiver structure for the reverse link of a code-division multiple-access communication system, in the presence of multipath effects and using an antenna array at the base ...
