Receiver system for decoding data embedded in an electromagnetic signal

A receiver for decoding data configured in a plurality of data blocks, comprising:

• a first tuner operative to demodulate a first electromagnetic signal;
• a second tuner operative to demodulate a second electromagnetic signal that comprises the plurality of data blocks, and decode the plurality of data blocks;
• where the second tuner is operative to switch from the non-diversity function to the diversity function based on the time interval between successive data blocks;
• and
• a timer in communication with the second tuner and operative to estimate a time interval between data blocks, where the second tuner is initialized with the time interval estimate and operative to switch from the non-diversity function to the diversity function between successive data blocks.
