International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California / The selection of the Intermediate Frequency (IF) bandwidth filter for a data receiver for
processing PCM data is based on using a peak deviation of 0.35 times the bit rate. The
optimum IF bandwidth filter is equal to the bit rate. An IF bandwidth filter of 1.5 times the
bit rate degrades the data by approximately 0.7 dB. The selection of the IF bandwidth
filter for tracking receivers is based on the narrowest “noise bandwidth” that will yield the
best system sensitivity. In some cases the noise bandwidth of the tracking receiver is the
same as the IF bandwidth of the data receiver because it is the same receiver. If this is the
case, the PCM bit rate determines the IF bandwidth and establishes the system sensitivity.
With increasing bit rates and increased transmitter stability characteristics, the IF
bandwidth filter selection criteria for a tracking receiver must include system sensitivity
considerations. The tracking receiver IF bandwidth filter selection criteria should also be
based on the narrowest IF bandwidth that will not cause the tracking errors to be masked
by high bit rates and alter the pedestal dynamic response.
This paper describes a selection criteria for a tracking receiver IF bandwidth filter based
on measurements of the tracking error signals versus antenna pedestal dynamic response.
Different IF bandwidth filters for low and high bit rates were used.
