-Fast Fourier Transform (FFT) processing is one of the key procedures in popular Orthogonal Frequency Division Multiplexing (OFDM) communication systems. Structured pipeline architectures, low power consumption, high speed and reduced chip area are the main concerns in this VLSI implementation. In this paper, the efficient implementation of FFT/IFFT processor for OFDM applications is presented....

Introduction: Audio technology has come a long way from magnetic tape recording in the early twentieth century to the current digital music technology. The increase in Internet audio streaming and digital audio broadcasting poses a new challenge, as they are often subject to bandwidth limitation that is incompatible with the high data rate of digital music. However, with the current perceptual ...

Due to its high-performance broadcast capability, -ary phase-shift-keying (MPSK) direct sequence code division multiple access (DS/CDMA) technique is widely used in terrestrial and satellite communications to provide wired/wireless services such as audio broadcasting, video broadcasting and high-speed data transmission. However, both coherent and noncoherent MPSK modulation schemes are sensitiv...

In this paper, a person tracking sensor based multi-channel audio panning approach is proposed for multi-view broadcasting services. Multi-view broadcasting is realized by rendering the video sequences captured by a set of cameras from different viewpoints. In addition, a multi-channel audio panning technique is required for realistic audio rendering. Moreover, person-tracking techniques for es...

The Digital Video Broadcasting (DVB) Project was founded in 1993 by the European Telecommunications Standards Institute (ETSI) with the goal of standardizing digital television services. Its initial standard for satellite delivery of digital television, dubbed DVB-S, used a concatenation of an outer (204,188) byte shortened Reed Solomon code and an inner constraint length 7, variable rate (r ra...

Digital multimedia broadcasting is available in more and more countries with various forms. One of the most successful forms is Digital Video Broadcasting for Terrestrial (DVB-T), which has been deployed in most countries of the world for years. In order to bring the digital multimedia broadcasting services to battery-powered handheld receivers in a mobile environment, Digital Video Broadcastin...
