Notes

1. This model can be used to descramble the DATA field, according to IEEE 802.11a standard. The structure is the same as scrambler, as shown in Fig.1. For details, please refer to the model SCRM11a.

Fig.1 Data descrambler

Netlist Form

DSCRM11A:NAME n1 n2 [MODULATION =val] [CODING =val]
+ [LENGTH =val] [S0=val] [RIN=val] [ROUT=val]

Netlist Example

DSCRM11A:1 1 2 MODULATION = 2 CODING= 2 LENGTH = 100 S0 = 93
