Abstract

A method and apparatus are provided for encoding an information object. The method includes storing the information object in a buffer; generating a sampling set including bits selected from the buffer according to a predetermined rule and bits randomly selected from the buffer; generating control channel data including information on the sampling set; and modulating the sampling set and the control channel data.

Claims

1. A method for encoding an information object, the method comprising the steps of:

storing the information object in a precoder buffer;

generating a sampling set including bits selected from the precoder buffer according to a predetermined rule and bits randomly selected from the precoder buffer;

generating control channel data including size information on the information object; and

modulating the sampling set and the control channel data.

2. The method of claim 1, wherein the control channel data further includes a sampling set number of the sampling set.

3. The method of claim 1, further comprising repeating and interleaving bits of the information object, before storing the information object.

4. The method of claim 3, further comprising encoding the repeated and interleaved bits of the information object by using a predefined code, before storing the information object.

5. An apparatus for encoding an information object, the apparatus comprising:

a precoder buffer; and

an encoder configured to;

store the information object in the precoder buffer;

generate a sampling set including bits selected from the precoder buffer according to a predetermined rule and bits randomly selected from the precoder buffer;

generate control channel data including size information on the information object; and

modulate the sampling set and the control channel data.

6. The apparatus of claim 5, wherein the control channel data further includes a sampling set number of the sampling set.

7. The apparatus of claim 5, wherein the encoder is configured to repeat and interleave bits of the information object, before storing the information object.

8. The apparatus of claim 7, wherein the encoder is configured to encode the repeated and interleaved bits of the information object by using a predefined code, before storing the information object.
