1. 802.16e WiMAX signal configuration: bandwidth: 10 MHz, FFT: 1024, frame length: 5 ms,
guard period: 1/8, symbol rolloff: 5%, content: 30 symbols of PN9 data.
2. Measurement configuration: reference channel integration BW: 9.5 MHz, offset channel
integration BW: 9 MHz, channel offset: 10 MHz.
3. This is rms power. How to convert from rms to peak envelope power (PEP): PEP = rms
power + crest factor. Example: 3GPP test model 1 with 64 DPCH has a crest factor >11 dB,
therefore at +5 dBm rms, the PEP = 5 dBm + 11 dB = +16 dBm PEP.
