摘要： A method of closed-loop antenna tuning (CLAT) search strategy based on maximum Relative Transducer Gain (RTG) is proposed. A search region that account for TX input mismatch and forward voltage gain is pre-computed. The search region that is independent of antenna load can be pre-computed to reduce the computation complexity. The Maximum RTG is searched by estimating antenna S-parameters corresponding to a good load match. The search is conducted between the peak forward voltage gain and the best load match. Global optimal with reasonable RTG can be found with limited number of iterations. The transmitter search region can further be constrained by the receiver path mismatching.

摘要： A communications apparatus has a transmitter path and a training signal generator. The transmitter path is arranged for transmitting a transmission signal. The training signal generator is arranged for generating a training signal in a receiver band, and injecting the training signal to the transmitter path. The training signal is utilized to obtain an accurate estimation of the channel which helps to suppress transmission noise comprised in at least one received signal of the communications apparatus, and the transmission noise is generated by the transmitter path. Specifically, the communications apparatus further has a receiver path and a transmission noise suppression device. The receiver path is arranged for receiving a received signal. The transmission noise suppression device is arranged for receiving the training signal, and processing the received signal to suppress transmission noise comprised in the received signal according to at least the training signal.
