Clock Offset Tracking Performance
The PRISM baseband processor is designed to accept data
clock offsets of up to
±
25ppm for each end of the link (TX
and RX). This effects both the acquisition and the tracking
performance of the demodulator. The budget for clock offset
error is 0.75dB at
±
50ppm. No appreciable degradation was
seen for operation in AWGN at
±
50ppm.
Carrier Offset Frequency Performance
The correlators used for acquisition for all modes and for
demodulation in the 1 and 2Mbps modes are time invariant
matched filter correlators otherwise known as parallel
correlators. They use two samples per chip and are tapped
at every other shift register stage. Their performance with
carrier frequency offsets is determined by the phase roll rate
due to the offset. For an offset of +50ppm (combined for both
TX and RX) will cause the carrier to phase roll 22.5 degrees
over the length of the correlator. This causes a loss of
0.22dB in correlation magnitude which translates directly to
Eb/N0 performance loss. In the PRISM chip design, the
correlator is not included in the carrier phase locked loop
correction during acquisition.
