The paper describes a proposed physical layer in the implementation of a direct sequence code division multiple access (DS-CDMA) ultra wide band (UWB) radio system. Performance of the system is examined with (i) a traditional receiver, (ii) an MMSE r

We present adaptive signal processing prediction architectures for narrowband interference (NBI) suppression for spread spectrum communication systems. The presented adaptive algorithm uses only 1-bit signals obtained from a front-end bandpass /spl S

Conference Record of the Thirty-Fourth Asilomar Conference on Signals, Systems and Computers (Cat. No.00CH37154).
We present three joint adaptive mean squared error receiver structures for a time division duplex down-link scenario in which a single mobile station is allocated several code-multiplexed channels. The first structure is a bank of single channel MMSE

DSP system-level design decisions can have significant effects on field programmable gate array (FPGA) hardware cost and efficiency. In this paper we demonstrate how modifying filter coefficients and taking advantage of non-canonical implementation t

Channel estimation is a key step in the initial synchronisation of a RAKE receiver. In this paper we present an algorithm for multipath channel estimation based on an elegant and efficient new technique for resolving the multipath components. The per

A modified version of the minimum mean square error receiver to be used with UTRA TDD mode is presented in this paper. The structure is tested in a multipath fading channel and its equalisation and multipath access interference suppression characteri
The potential presence of fractional delays, non-minimum phase parts, and a colouring of the channel output can require adaptive equalizers to adapt very long impulse responses. Besides resulting in a large computational complexity, this will in gene

In this paper an adaptive structure based on the minimum mean square error receiver for the downlink in W-CDMA is presented. The set up enables the suppression of multiple access interference, and implements channel equalization, thus reducing multip

In this paper we present a library for the rapid prototyping of adaptive signal processing algorithms, architectures and applications. The library is hosted by the DSP simulation software SystemView and covers virtually the complete spectrum of linea
