This paper presents a 40-Gbit/s time-division multiplexing (TDM) system prototype based on InP HEMT digital IC technologies. High-output power photodiode directly drives the digital IC and achieves high-receiver sensitivity. Four-channel 40-Gbit/s wavelength-division multiplexing (WDM) transmission is successfully performed.
This paper presents a noise-robust, fast-convergence echo canceller and its implementation on a multimedia RISC (Reduced Instruction Set Computer). Faster convergence is achieved by introducing an improved noise power estimator for step-size control. This echo canceller has been implemented on V830 multimedia embedded RISC and has been integrated into a car… (More)
Motion Estimation (ME) is an integral part of any video encoder and a large number of Block Matching Motion Estimation (BMME) Algorithms are proposed to cope the computational complexity and increase quality of ME process requirement. Therefore, it is necessary to evaluate the performance of these ME algorithms for different motion activities. In this paper… (More)
