Claim 17) which deals with "....a fourth arrangement configured to determine an interference carrier frequency in accordance with tuning a PLL source....."
The interference carrier frequency is determined by tuning a PLL source. Providing such a PLL source in the reception branch makes a variable carrier dispensable. However, an increased circuit complexity is necessary in the respective frequency range, e.g., in the range of 2 GHz.
