Patent ID: 7088766

Claim:
A medium storing program instructions, executable on a computer system for dynamic measurement of a communication channel using a Direct Sequence Spread Spectrum (DSSS) communication system to perform the following steps: (a) generating a Pseudo Noise (PN) code signal (f 0 =1/T) having a length (I), where f 0 =PN code signal bandwidth, and T=PN code signal chip rate; (b) modulating a carrier (cos. 2πf c ) with the PN code signal, where f c =carrier frequency and the carrier frequency varies among a plurality of predetermined carrier frequencies; (c) modulating the PN coded carrier with a data signal as a PN coded data carrier signal; (d) providing the PN coded data carrier signal to a correlator via a communication channel for determining transmission characteristics of the communication channel; and (e) determining a correlator value for each of the plurality of predetermined frequencies of the carrier from the PN coded data carrier signal, where the correlator values are a measure of attenuation loss of the communication channel.
