Abstract
An apparatus and method for improving the signal reception of a digital wireless receiver comprises a processing circuit for processing the preamble information of incoming signals, wherein a first predetermined portion of the preamble information is applied to a first antenna and a second predetermined portion of the preamble information is applied to a second antenna to produce a plurality of processed signals, such that the plurality of processed signals is compared to a predefined preamble sequence to obtain a mean-square error (MSE) for the respective antenna. Then, one of the first and second antennas with a lower MSE is selected to receive and process the incoming signals.
Claims22
A method for enhancing the signal reception of a digital wireless receiver, the method comprising the steps of:
- extracting a preamble information from a plurality of incoming signals;
- processing a first predetermined portion of said preamble information with a first antenna to produce a first preamble sequence;
- processing a second predetermined portion of said preamble information with a second antenna to produce a second preamble sequence;
- calculating a mean-square error (MSE) for said first preamble sequence received from said first antenna and said second preamble sequence received from said second antenna;
- and,
- selecting one of said first antenna and said second antenna having a lower MSE for subsequent reception of said incoming signals.
A method for enhancing the signal reception of a digital wireless receiver, the method comprising the steps of:
- receiving a plurality of incoming signals;
- dividing the header information of said incoming signals to process said divided header information by a first antenna and a second antenna;
- comparing said processed header information from said first antenna and said second antenna with a predefined preamble sequence to obtain a mean square error (MSE);
- and,
- selecting one of said first antenna and said second antenna having a lower MSE for subsequent reception of said incoming signals.
