Baseband receiver and method of using same

An automatic gain control process for a baseband receiver, comprising:

• amplifying a baseband signal using a gain setting;
• digitizing the amplified baseband signal into a series of digital data points;
• incrementing a counter for data point values that exceed a numerical threshold in a time period;
• comparing, after the time period, the counted data points to a count threshold;
• lowering the gain setting if the number of counted data points exceeds the count threshold;
• and
• amplifying the baseband signal using the lowered gain setting.

A process for detecting a data frame using a baseband receiver, the process comprising:

• providing a baseband signal that includes a series of like symbols, each symbol having a symbol period;
• digitizing the baseband signal at a rate sufficient to generate a set of data points for each of a plurality of symbol periods;
• dividing each set of data points into a first subset and a second subset;
• correlating the first subset from one symbol period with the first subset from another symbol period, the correlation generating a correlation result;
• defining a correlation threshold;
• comparing the correlation result with the threshold;
• and
• detecting, if the correlation result exceeds the threshold, that the series of like symbols has been located.

A baseband receiver process, comprising:

• amplifying a baseband signal;
• digitizing the amplified baseband signal into complex digital baseband data;
• selecting only one bit of resolution for the baseband data;
• receiving complex reference data;
• selecting only one bit of resolution for the reference data;
• and
• correlating the digital baseband data with the reference data.
