Lyapunov Functions and Martingales,, we present an overview of what has come to be known as wideband CDMA (WCDMA). While no precise definition of such a waveform exists, the concepts behind a WCDMA design are simple to state. Minimally, one would want to be able to efficiently support high data rate multimedia traffic, as well as mak作者: 整頓 時間: 2025-3-22 09:28
Lyapunov Functions and Martingales,rictions, modulation schemes other than QPSK and π/4-DQPSK are desirable. A possible candidate to achieve higher spectral efficiency is M-ary QAM, in particular 16-QAM. In this paper we investigate novel non-data-aided techniques for carrier recovery with 16-QAM preambless transmission. In particula作者: vector 時間: 2025-3-22 14:05
Manufacturing and Re-manufacturing Systems, large amount of computing power is required but also highly linear data converters. In this paper, we present a concept which reduces the dynamic range of the A/D converter in the receive path by substracting a coarse analog echo estimate from the received signal. Such a coarse estimate is built wi作者: Anthrp 時間: 2025-3-22 17:28

Introduction to Continuous Timeen interference levels rise, requiring the use of further signal processing to combat interference. Traditionally, the approach has been to excise the interference by either estimating it and then subtracting it, or by filtering it out.

Iterated Soft-Decision Interference Cancellation for CDMArence scenarios. In this paper, it is shown how this detection scheme can be further improved by adaptive calculation of the soft-decision rule. This enables a significantly higher number of active users signaling within the same bandwidth to be detected, implying that spectral efficiency is increased.作者: Lumbar-Stenosis 時間: 2025-3-25 18:22 作者: Agnosia 時間: 2025-3-25 22:01 作者: GEST 時間: 2025-3-26 01:32
