help me model GSM, UMTS and WiFi on the software Optisystem

I want to model on the software Optisystem the various standards, using a VCSEL laser at 850nm, a multimode fiber 300 m in length and a photodetector pin.

GSM:
Carrier 2 GHz 900 MHz
GMSK modulation

UMTS:
2GHz carrier
QPSK modulation
Debit 3.84Msyn / s

DPRS:
1.88GHz carrier
Modulation pi / 4 DQPSK
Debit 1.152Msyn / s

DPRS
1.88GHz carrier
Modulation pi / 8 D8PSK
Debit 1.152Msyn / s

:idea:
IEEE 802.11a IEEE
5825 GHz carrier
Modulation 64QAM - OFDM
Throughput 54 Mbit / s

IEEE 802.11b
2.412GHz Carrier
CCK modulation - DSSS
Speed 11 Mbps.
I have already started, but I can not find the constellation diagram and the eye and to transmit the VCSEL, fiber optics and also pin PHOTODETECTOR no signal.
Does someone can help me? Thank you very much.
