Abstract
A radio receiver is disclosed, comprising: a receiving stage configured to receive a multi-layered signal comprising a plurality of layers; a division stage configured to divide the plurality of layers into a first subset and a second subset; a first whitening filter configured to filter the multi-layered signal based on a noise and interference covariance measure derived from the second subset to provide a first filtered multi-layered signal; and a first detection stage configured to detect at least one layer of the first subset based on the first filtered multi-layered signal.
Claims24
A radio receiver, comprising:
- a demultiplexer configured to receive a multi-layered signal comprising a plurality of layers, and
- to divide the plurality of layers into a first subset and a second subset;
- a first whitening filter configured to filter the multi-layered signal based on a noise and interference covariance measure calculated for each of the first subset and the second subset such that the noise and interference covariance measure is derived from the second subset to provide a first filtered multi-layered signal, and the noise and interference covariance measure is derived from the first subset to provide a second filtered multi-layered signal;
- and
- a first detection filter configured to detect at least one layer of the first subset based on the first filtered multi-layered signal.
A radio receiver, comprising:
- a demultiplexer configured to receive a four-layered signal,
- and to divide the four-layered signal into a first two-layered signal and a second two-layered signal;
- a whitening filter configured to filter the four-layered signal based on a noise and interference covariance matrix derived from the second two-layered signal to provide a first filtered signal;
- a first detection filter configured to detect at least one layer of the first two-layered signal based on the first filtered signal.
A radio receiver, comprising:
- a demultiplexer configured to receive a four-layered signal, and
- to divide the four-layered signal into a one-layered signal and a three-layered signal;
- a whitening filter configured to filter the four-layered signal based on a noise and interference covariance matrix derived from the three-layered signal;
- and
- a detection filter configured to detect a layer of the one-layered signal based on the four-layered signal filtered by the whitening filter.
A method for detecting a layer of a multi-layered signal, the method comprising:
- receiving a multi-layered signal comprising a plurality of layers;
- dividing the plurality of layers into a first subset and a second subset;
- filtering the multi-layered signal based on a first noise and interference covariance matrix derived from the layers of the second subset;
- and
- detecting at least one layer of the first subset based on the multi-layered signal filtered by first noise and interference covariance matrix;
- filtering the multi-layered signal based on a second noise and interference covariance matrix derived from the layers of the first subset;
- and
- detecting at least one layer of the second subset based on the multi-layered signal filtered by the second noise and interference covariance matrix.
