Abstract: A slot-based low Intermediate Frequency (‘IF’) radio receiver comprises an IF local oscillator (3, 5, 19) for producing I and Q IF local oscillator signal components in phase quadrature, I and Q mixer channels (4, 6) for mixing the input signal with the I and Q IF local oscillator signal components to produce I and Q IF signal components. The IF local oscillator (3, 5, 19) includes frequency alternation means (20) for causing the IF local oscillator frequency to alternate a plurality of times during each frame between first and second values, one of which is greater and the other smaller than the desired carrier frequency of the input signal so as to reduce the effect of adjacent and alternate interferers.The phase of the baseband local oscillator (12, 13) is alternated in synchronism with the alternation of the IF local oscillator frequency.

Abstract: A slot-based radio signal at a carrier frequency is received, the radio signal including successive frames, each frame including a set of reception time slots, to producing an input signal. A local oscillator signal is produced, In-phase and Quadrature components having a local oscillator frequency. The input signal is mixed with the local oscillator signal and Intermediate Frequency signal In-phase and Quadrature components are produced. The local oscillator frequency of the local oscillator signal changes relative to the carrier frequency of the input signal multiple times during the reception time slots of each of the frames between two frequency values. One frequency is greater and the other frequency is smaller than the carrier frequency. Frequencies of Intermediate Frequency components are selectively passed within a low Intermediate Frequency range and frequencies outside said low Intermediate Frequency range are rejected so as to produce filtered signal components.
