WIRELESS MULTIMEDIA CONTINUOUS PACKET CONNECTIVITY (CPC), POWER AMPLIFIER (PA) BACK-OFF AND THE CUBIC METRIC (CM)

Terence E. Dodgson, Mark Horgan

Abstract

With the every-increasing complexity of (e.g. multi media) signal waveforms generated by transmitters of modern digital communications systems, there comes a corresponding demand for transmitters to continue to operate efficiently (e.g. from a cost per bit and power output point of view) and to produce minimum distortion, within specified limits. This paper looks at how a particular CPC scheme (for efficient resource usage) might be devised and what the resulting impact is on the CM measure. The work uses, as a basis for simulations, mainly the Uplink of the third generation (3G) Wideband Code Division Multiple Access (WCDMA) Release six (R6) system.
