A wireless communication arrangement includes a transmitter that transmits a signal having a carrier that repeatedly and sequentially hops through a first sequence of frequencies. A receiver includes a mixer having an antenna signal input for receiving an antenna signal, and a local oscillator for generating a local oscillator signal and providing the local oscillator signal to a local oscillator input of the mixer. The local oscillator signal repeatedly and sequentially hops through a second sequence of frequencies having fewer members than the first sequence of frequencies and the repetition frequency with which the local oscillator signal hops through the second sequence of frequencies is substantially equal to the repetition frequency with which the carrier hops through the first sequence of frequencies. Preferably, the receiver includes an ADC that is sampled at a rate greater than twice the bandwidth of the antenna signal.
