TRANSMITTER WITH INTELLIGENT PRE-CONDITIONING OF AMPLIFIER SIGNAL

摘要

A transmitter (20) for a code division multiple access radio access netwo rk intelligently preconditions a channel-merged signal which is applied to i ts amplifier (22) so that the amplifier does not experience, e.g., precipito us power changes. The transmitter (20) comprises an amplifier (22) for ampli fying the channel- merged signal at a signal output power; a detector (24) f or performing detection of when output power of the channel-merged signal is about to change by a specified amount; and, a noise inserter (26) for addin g a noise signal to the channel-merged signal in dependence upon the detecti on. Insertion of the noise smoothes an edge of the power change curve and th ereby averts stress for the amplifier.
