Abstract
A communication apparatus comprising a receiver and a transmitter for receiving/transmitting signals in the range of 100 kHz to 100 MHz. A controller is configured to cause a clock signal used by one of the receiver and the transmitter part with to be offset with respect to a clock signal used by the other of the receiver and the transmitter. A switch arrangement is provided between an input and output, and the receiver and the transmitter. The switch arrangement is configured to switch between the receiver and the transmitter during a clock cycle such that, in use, part of a clock cycle is available for signal transmission and part of the clock cycle is available for signal reception.
Claims15
A communication apparatus, comprising:
- an input configured to receive a signal in the range of 100 khz to 100 mhz;
- a receiver configured to receive the signal from the input;
- an output configured to output the signal in the range of 100 kHz to 100 MHz;
- a transmitter configured to provide the signal to the output;
- a controller configured to cause a clock signal used by one of the receiver and the transmitter to be offset with respect to the clock signal used by the other of the receiver and the transmitter;
- and
- a switch provided between the input and the output, and the receiver and the transmitter;
- wherein the switch is configured to switch between the receiver and the transmitter during the clock cycle such that a part of the clock cycle is available for signal transmission and another part of the clock cycle is available for signal reception.
The communication apparatus as claimed in 9, wherein said controller is configured in said first mode to determine a time offset for said clock signal.
A signal processing method, comprising:
- receiving a signal in a range of 100 kHz to 100 MHz or transmitting a signal in the range of 100 kHz to 100 MHz using a first clock signal;
- switching to the other one of receiving or transmitting the signal using a clock signal that is offset with respect to the first clock signal, wherein the switching is such that during a clock cycle one part of the clock cycle is used for transmitting the signal and another part of the clock cycle is used for receiving the signal.
