A VLSI Architecture for a High-Speed All-Digital Quadrature Modulator and Demodulator for Digital Radio Applications
Abslruer-An all-digital architecture is presented for implementing the front-end signal processing functions in a quadrature modulator and demodulator for high bit-rate digital radio applications. A pair of CMOS chips has been designed and submitted for fabrication in a 1.25 pm process and is expected to accommodate symbol rates up to 35 MBd. The modulator chip accepts a pair of 8 b in-phase an...
متن کاملAn efficient VLSI architecture for digital geometry
of Contributions The main contribution of this work is to show that a number of fundamental digital geometry tasks can be solved fast on a novel VLSI architecture obtained by augmenting the mesh with multiple broadcast architecture (MMB) with precharged 1-bit row and column buses. The new architecture that we call mesh with hybrid buses (MHB) is readily implementable in VLSI with no increase in...
متن کاملDigital Audio Broadcasting: An Interactive Services Architecture
Digital Media Technologies offer enhanced multimedia signal broadcasting and description of the signal on content. Digital Audio Broadcasting (DAB) is a media standard with extended multimedia capabilities, offering novel services to users worldwide. Each digital broadcasting standard though, cannot be separately viewed from the development of Internet radio broadcasting. In this paper we intro...
متن کاملDigital Video Broadcasting Conditional Access Architecture
Digital Video Broadcasting (DVB) is a standard defining a one-to-many unidirectional data network for sending digital TV programs over satellite, cable, and other topologies. The standard enables the broadcasting industry to offer hundreds of pay-TV channels to consumers. The expanded capacities make the broadcast signals more valuable and attractive to signal thefts [1]. To protect a DVB data-...
متن کاملDesign and Implementation of Digital Demodulator for Frequency Modulated CW Radar (RESEARCH NOTE)
Radar Signal Processing has been an interesting area of research for realization of programmable digital signal processor using VLSI design techniques. Digital Signal Processing (DSP) algorithms have been an integral design methodology for implementation of high speed application specific real-time systems especially for high resolution radar. CORDIC algorithm, in recent times, is turned out to...
