Class Information
Number: 375/347
Name: Pulse or digital communications > Receivers > Interference or noise reduction > Diversity (frequency or time)
Description: Subject matter including two separate receivers receiving the same signal on two different frequencies or at two different locations on the same frequency or one receiver receiving the same signal at different times and combining the two thus received signals into a more noise free signal.
