We propose a new scheme for adaptive quantization which is particularly well suited to the digital implementation of PCM and DPCM structures.
Recently, an adaptive peak cancellation was proposed to reduce the high peak-to-average power ratio (PAPR), while keeping the out-of-band (OoB) power leakage as well as an in-band distortion power
An adaptive linearizer for reducing channel nonlinearities in QAM data transmission systems is described and its performance is evaluated.
A multimedia call consists of three main sub-streams (i.e. video, audio and data) each with its own distinct quality of service (QoS) requirements (e.g.
In this article we address the problem of link adaptation in a wireless data system.
We describe a novel approach to the design of adaptive load sharing algorithms for a class of multiprocessor systems.
Multiple transmit and receive antennas, more generally known as multiple-input multiple-output (MIMO) systems, are used in an extension to the third generation partnership program (3GPP) standard c
For orthogonal frequency-division multiplexing (OFDM) systems, the frequency offsets in mobile radio channels distort the orthogonality between sub-carriers that results in intercarrier interferenc
Bit rate reduction from the present 64 kb/s per trunk is of interest both to reduce per-trunk cost of existing and planned digital transmission facilities and to prove-in digital transmission.
In this paper we describe the demonstration of a four level interconnection enhancement of our 0.9 micron CMOS technology.
