Abstract

A method for encoding an information object in a communication system by storing the information object in a buffer; generating a sampling set including bits randomly selected from the buffer and bits regularly selected from the buffer; generating control channel data including a sampling set number of the sampling set and size information for the information object; and modulating the sampling set and the control channel data.

Claims

1. A method for encoding an information object in a communication system, the method comprising the steps of:

storing the information object in a buffer;

generating a sampling set including bits randomly selected from the buffer and bits regularly selected from the buffer;

generating control channel data including a sampling set number of the sampling set and size information for the information object; and

modulating the sampling set and the control channel data.

2. The method as claimed in claim 1, further comprising repeating and interleaving bits of the information object, before storing the information object.

3. The method as claimed in claim 2, further comprising encoding the repeated and interleaved information object by using a predefined code, before storing the information object.

4. An encoder comprising:

a precoder for encoding the information object and storing the encoded information object in a precoder buffer;

a sample number/address generator for generating a sampling set number and addresses of the precoder buffer, corresponding to bits randomly selected from a sampling set and bits selected according to a predetermined rule from the sampling set;

a multiplexer for selecting the bit of the precoder buffer, corresponding to the address generated by the sample number/address generator;

a sampling set buffer for storing the sampling set output from the multiplexer;

a control packet generator for generating control channel data including information on the sampling set number generated by the sample number/address generator;

a packet assembler for assembling the sampling set stored in the sampling set buffer with the control channel data generated by the control channel generator; and

a modulator for modulating a packet output from the packet assembler in a predefined scheme.

5. The encoder as claimed in claim 4, wherein the sample/address generator comprises:

a random address generator for outputting a random value; and

a regular address generator for outputting a regular value according to a predefined rule.

6. The encoder as claimed in claim 4, wherein the precoder further comprises a sampling set number generator for generating the sampling set number for use in identification of the sampling set in a predefined cycle.

7. The encoder as claimed in claim 4, wherein the precoder comprises:

a container packer for adding a header label to the information object and setting bits for integrity check to thereby pack the information object into a standard container; and

a repeater/interleaver for repeating and interleaving output data from the container packer.

8. The encoder as claimed in claim 7, wherein the precoder further comprises a convolution encoder for performing convolution code encoding of data output from the repeater/interleaver and storing the encoded data in the precoder buffer.
