Power Control for Packet Voice Service With Application to EDGE Wireless System

Overview Transmission power control has been widely practiced to manage interference in cellular networks [Z92] [EKB96] [RZ98]. Existing algorithms can be classified as signal-based [HWJ97] and signal-to-interference-ratio (SIR) based [Z92] [FM93] power control. SIR-based power control iteratively adjusts power according to previous SIR measurements, and typically performs well for calls with relatively long holding time. The purposes of this paper are twofold. First, it explores the applicability and quantifies the performance gain of the Kalman power control for packet voice service in the EDGE system. Second, it examines exchange of control information needed for the power-control method.

The Ovum view: Going over the Edge

Most versions of the roadmap show separate but aligned paths for the four main digital cellular families - the largely European GSM, the US TDMA and CDMA standards, and the Japanese PDC. The latter offers a tripling of the network capacity of GPRS...

3G: Boldly going where no one should have gone in the first place?

One of the winners of the Finnish cellular pageant was Sonera. For instance, the GSM network, supported by EDGE (enhanced data rates for global evolution) and GPRS (general packet radio service), can now increase the bandwidth available.

Peter Cochrane's Blog: Wireless jelly

For at least some of the time I think we can safely assume that the problem is plain old interference. It appears that mains- or power-feed borne interference is still getting into the environment and causing an occasional problem.

Radioactive: Bluetooth - survival of the fastest

This increases the signal's range by reducing interference. The former method, backed by Intel, is more complex: it chops up the signal and sends it over multiple frequency bands. The other approach sends out the signal in a single stream which...

Peter Cochrane's Blog: Aerial bombardment

Once the desired antenna propagation characteristics have been achieved, then it is usual that some closely located system causes interference on one kind or another. Until that day, we will have to continue the struggle for antenna real estate and...

Peter Cochrane's Blog: The search for spectrum

This is the world I grew up in as a young engineer, where interference, multi-path, scatter and signal-to-noise ratio dominated all design and operational considerations. They talk to each other to minimise the energy used and problems associated...
