Abstract
A receiver includes one or more mixers configured to sample an input analog signal at a plurality of discrete points in time to obtain a discrete-time sampled signal based on a local oscillating signal provided by a local oscillator; and a sample reordering circuit coupled to the one or more mixers and configured to reorder a sequence of samples received from the one or more mixers.
Claims12
A receiver, comprising:
- one or more mixers configured to sample an input analog signal at a plurality of discrete points in time to obtain a discrete-time sampled signal, having a sequence of a plurality of samples, based on a local oscillator signal provided by a local oscillator;
- and
- a sample reordering circuit coupled to the one or more mixers and configured to reorder the sequence of the plurality of samples received from the one or more mixers to a different sequence of the plurality of samples.
A method for processing an input analog signal, the method comprising:
- sampling, at one or more mixers, the input analog signal at a plurality of discrete points in time to obtain a sampled signal, having a sequence of a plurality of samples, based on a local oscillator signal;
- and
- reordering the sequence of the plurality of samples in the sampled signal to a different sequence of the plurality of samples.
A non-transitory computer-readable medium having stored therein instructions that, when executed by a processor of a controller, perform a method for processing an input analog signal, the method comprising:
- sampling, at one or more mixers, the input analog signal at a plurality of discrete points in time to obtain a sampled signal, having a sequence of a plurality of samples, based on a local oscillator signal;
- and
- reordering, by a sample reordering circuit, the sequence of the plurality of samples in the sampled signals to a different sequence of the plurality of samples.
