Abstract
In order to reduce the noise components in a multiplexed communication system, noise components generally referred to as splatter that from the rapid transition between the transmitting state and the non-transmitting state, this power transition in the transmitted signal is provided with a ramped envelope. In the preferred embodiment, the ramped power transition is the result of a ramped enabling signal applied to the power amplifier generating the transmitted signal. The use of a ramped power transition reduces the noise introduced as a result of an abrupt power transition. In addition, the transmitted signal is provided with a preamble so that no data is transmitted during the transition period.
