What kind of Baseband filter for P-SS?
The LTE standard does not specify what transmitter filter to use. For the transmitter in ADS, we use ideal low pass filter or RRC filter; for signal studio, we use ideal low pass filter to filter baseband signal, no specific filtering on P-SS. In TD-LTE signal analyzer, we do not use any additional receiving filter except that N9020A MXA filters the input signal according to span for different bandwidth.
