摘要:
A controller is configured to determine a word in a set of words corresponding to a received coding value, the set of words including at least one data word, at least one modulator command word and at least one gain command word. When the received coding value corresponds to a data word, the controller causes the data word to be modulated. When the received coding value corresponds to a modulator command word, the controller controls a modulator based on the modulator command word. When the received coding value corresponds to a gain command word, the controller controls a gain based on the gain command word.
