Abstract
A transceiver for time-domain duplexed (TDD) communications, for example in connection with wireless broadband data communications, is disclosed. The transceiver includes digital predistortion compensation circuitry, which compensates the digital signals to be transmitted based on feedback signals from the output of the power amplifier, in order to linearize the output from the power amplifier. The feedback signals from the power amplifier are coupled back to the digital predistortion circuitry over part of the same receive path as the received signals from the wireless communications channel. The shared path includes analog-to-digital converters that are used both in the transmit period of the TDD cycle to convert the feedback signals from the power amplifier output, and in the receive period of the TDD cycle to convert the analog received signals.
