Abstract
A method of monitoring a transmission includes obtaining one or more values of bit error rate (BER) of the transmission received at a receiver; and determining that the transmission has been intercepted based on a deviation of the obtained bit error rate value from an expected bit error rate value.
Claims21
A method of monitoring a transmission, the method comprising:
- obtaining one or more values of bit error rate (BER) of the transmission received at a receiver;
- and
- determining that the transmission has been intercepted based on a deviation of the obtained bit error rate value from an expected bit error rate value.
A method for transmitting a transmission to a receiver, the method comprising:
- setting a parameter of the transmission such that the transmission is to have a first signal to noise ratio (SNR) at the receiver;
- and
- causing the transmission to be transmitted according to the set parameter, wherein
- a critical value, SNRcrit, is a SNR value at a minimum in d(BER)/d(SNR) with SNR, where BER is the bit error rate at the receiver, and
- a difference between the first SNR and a critical value is less than a full width at half maximum of d(BER)/d(SNR) with SNR.
