Figure 13. Sample Block Diagram for a Cordless Phone System
In Figure 13, a simple cordless phone system block diagram is shown. Note that the setup in the base
station will be slightly different than that for the handset. For simplicity, only a generic block diagram
is shown.

Figure 14. Sample Block Diagram for a Data Modem
In Figure 14, a sample block diagram for a data modem is shown. Note that the block diagram shown
is for a synchronous data modem; for an asynchronous data modem, a external rate adaption circuitry
is required to converter the asynchronous rate to synchronous rate.
PN SEQUENCE AND UW SELECTION
Four 32-bit PN (Pseudo Noise) sequences and one 22-bit Unique Word (UW) are required for each
spread spectrum communication device. Together, they can constitute a "security code" or
"identification code" which can be use to distinguish different users and ensure privacy. In addition,
the PN sequences and UW participate in the signal acquisition and burst synchronization processes.
