In 揚erformance of multi-carrier DS CDMA Systems?we apply a multi-carrier signaling technique to a direct-sequence CDMA system, where a data sequence multiplied by a spreading sequence modulates multiple carriers, rather than a single carrier. The receiver provides a correlator for each carrier, and the outputs of the correlators are combined with a maximal-ratio combiner. This type of signaling has the desirable properties of exhibiting a narrowband interference suppression effect, along with robustness to fading, without requiring the use of either an explicit RAKE structure or an interference suppression filter.

Abstract—The contourlet transform is a new two-dimensional
extension of the wavelet transform using multiscale and direc-
tional fi lter banks. The contourlet expansion is composed of
basis images oriented at various directions in multiple scales,
with fl exible aspect ratios. Given this rich set of basis images,
the contourlet transform effectively captures smooth contours
that are the dominant feature in natural images.
A programmable digital signal processor (PDSP) is a special-purpose microprocessor
with specialized architecture and instruction set for implementing DSP
algorithms. Typical architectural features include multiple memory partitions (onchip,
off-chip, data memory, program memory, etc.), multiple (generally pipelined)
arithmetic and logic units (ALUs), nonuniform register sets, and extensive
hardware numeric support [1,2]. Single-chip PDSPs have become increasingly
popular for real-time DSP applications [3,4].

While faster processors, larger memory, and powerful graphics are fundamental requirements for workstations, users
are also demanding a low-cost, solution-based approach wrapped around a standards-based technology. The Sun UltraTM
20 Workstation, which leverages the AMD OpteronTM processor with Direct Connect Architecture based on AMD64
technology, provides multiple operating system choices and leading nVidia graphics, delivers a platform that offers
flexibility and performance in a cost-effective package with solutions to benefit customers across the board.
