Abstract
Described herein are systems and methods for determining data rate in a direct sequence spread spectrum system. The systems may include circuits or processors for receiving a signal that was transmitted at an unknown data rate and determining the value of the unknown data rate based on a sequence of bits that is generated from processing the signal according to a first data rate. The methods may include receiving a signal having an unknown data rate, processing the signal according to a first data rate, generating another signal that corresponds to a sequence of bits that result from the processing, and determining the value of the unknown data rate according to the sequence of bits.

A method of determining data rate in a direct sequence spread spectrum system, the method comprising:
- receiving a signal that was transmitted at a particular data rate, wherein the particular data rate is unknown to a receiver, wherein the particular data rate is one of a high data rate or a low data rate, and wherein the high data rate is a binary multiple of the low data rate;
- processing the signal according to a first data rate, thereby generating a signal corresponding to a sequence of bits;
- and
- determining the particular data rate according to the sequence of bits.
A system for determining data rate in a direct sequence spread spectrum system, the system comprising:
- one or more circuits for receiving a signal that was transmitted at a particular data rate,
- wherein the particular data rate is unknown when received, wherein the particular data rate is one of a high data rate or a low data rate, and wherein the high data rate is a binary multiple of the low data rate;
- wherein the one or more circuits process the signal according to a first data rate, thereby generating a signal corresponding to a sequence of bits;
- and
- wherein the one or more circuits determine the particular data rate according to the sequence of bits.
A system for determining data rate in a direct sequence spread spectrum system, the system comprising:
- at least one processor for receiving a signal that was transmitted at a particular data rate,
- wherein the particular data rate is unknown when received, wherein the particular data rate is one of a high data rate or a low data rate, and wherein the high data rate is a binary multiple of the low data rate;
- wherein the at least one processor processes the signal according to a first data rate, thereby generating a signal corresponding to a sequence of bits;
- and
- wherein the at least one processor determines the particular data rate according to the sequence of bits.
A method of determining data rate in a communication system, the method comprising:
- receiving a direct sequence spread spectrum signal that was transmitted at a particular data rate, wherein the particular data rate is unknown to a receiver, wherein the particular data rate is one of a high data rate and a low data rate, and wherein the high data rate is a binary multiple of the low data rate;
- processing the direct sequence spread spectrum signal according to the high data rate, thereby generating a despread signal corresponding to a sequence of bits;
- determining the particular data rate according to an occurrence of repetition in the sequence of bits;
- and
- initiating proper decoding mechanisms for the particular data rate.
