Abstract
The method includes converting, by the receiver, an input signal into a return-to-zero (RZ) signal, generating, by the receiver, a first summation signal by performing an exclusive-or (XOR) operation on the RZ signal and a delayed signal obtained by delaying the RZ signal by a reference time, collecting, by the receiver, n-length seed codes from the first summation signal, generating, by the receiver, a PN code based on the seed codes, and generating, by the receiver, a second summation signal by performing an XOR operation on the PN code and the delayed signal.
Claims10
A method of acquiring a pseudo noise (PN) code at a receiver, the method comprising:
- converting, by the receiver, an input signal into a return-to-zero (RZ) signal;
- generating, by the receiver, a first summation signal by performing an exclusive-or (XOR) operation on the RZ signal and a delayed signal obtained by delaying the RZ signal by a reference time;
- collecting, by the receiver, n-length seed codes from the first summation signal;
- generating, by the receiver, a PN code based on the seed codes;
- and
- generating, by the receiver, a second summation signal by performing an XOR operation on the PN code and the delayed signal.
A receiver for acquiring a PN code, the receiver comprising:
- a first converter configured to convert an input signal input to the receiver into an RZ signal;
- a delayer configured to generate a delayed signal by delaying the RZ signal by a reference time;
- a first summer configured to perform an XOR operation on the RZ signal and the delayed signal;
- a seed estimator configured to collect n-length seed codes from an output signal of the first summer;
- a PN code generator configured to generate a PN code based on the seed codes;
- and
- a second summer configured to perform an XOR operation on the delayed signal and the PN code.
