Method of transmitting data in a mobile communication system
Disclosed is a data transmission method in a mobile communication system. The data transmission method through a code sequence in a mobile communication system includes grouping input data streams into a plurality of blocks consisting of at least one bit so as to map each block to a corresponding signature sequence, multiplying a signature sequence stream, to which the plurality of blocks are mapped, by a specific code sequence, and transmitting the signature sequence stream multiplied by the specific code sequence to a receiver.
1. A communication system, comprising:
a transmitter, the transmitter configured to:
create a consecutive sequence, wherein the consecutive sequence is created by concatenating a specific sequence one or more times, the specific sequence including code sequences of a same or different lengths;
append a single cyclic prefix to the front of the consecutive sequence to create a preamble sequence;
embed the preamble sequence into at least one of a plurality of signal frames; and
transmit the plurality of signal frames.
2. The communication system of claim 1 , wherein the preamble sequence includes at least a cyclic shift.
3. The communication system of claim 1 , wherein the specific sequence is a Constant Amplitude Auto Correlation (CAZAC) sequence.
4. The communication system of claim 1 , wherein transmitting the plurality of signal frames occurs over a Random Access Channel (RACH).
5. The communication system of claim 1 , wherein the consecutive sequence is encoded and interleaved.
6. The communication system of claim 1 , wherein concatenating the specific sequence is based at least in part on the data rate supported by the transmitter.
7. The communication system of claim 4 , wherein the RACH is used to access a network for communicating with a base station.
8. The communication system of claim 1 , wherein the transmitter includes one or more of a data sequence, a channel encoder, an interleaver, a signature mapping unit, and a CAZAC sequence generation unit for transmitting data and the preamble sequence in the plurality of signal frames.
9. A method comprising:
creating, by a transmitter, a consecutive sequence, wherein the consecutive sequence is generated by concatenating a specific sequence one or more times, the specific sequence including code sequences of a same or different lengths;
appending, by the transmitter, a single cyclic prefix to the front of the consecutive sequence to create a preamble sequence;
embedding, by the transmitter, the preamble sequence into at least one of a plurality of signal frames; and
transmitting, by the transmitter, the plurality of signal frames.
10. The method of claim 9 , wherein the preamble sequence includes at least a cyclic shift.
11. The method of claim 9 , wherein the specific sequence is a Constant Amplitude Auto Correlation (CAZAC) sequence.
12. The method of claim 9 , wherein transmitting the plurality of signal frames occurs over a Random Access Channel (RACH).
13. The method of claim 9 , wherein the consecutive sequence is encoded and interleaved.
14. The method of claim 9 , wherein concatenating the specific sequence is based at least in part on the data rate supported by the transmitter.
15. A non-transitory computer readable medium having instructions thereon that when executed by at least one processor of a wireless device perform a method comprising:
