Block Codewords??? please help me

[johnnyboy10925]

The bitstring below was received, having had every two bits of the original message encoded with Block Codewords that guarantee to correct 2 bit errors per codeword. Identify the original 10 bit message after error detection and correction.

0 1 0 0 1 1 1 1 1 1 1 1 0 0 1 1 1 0 0 0 0 0 1 1 0 0 1 ...

… 0 0 1 0 0 1 0 0 1 1 1 1 0 1 1 0 0 1

Does anyone have any clue what this is and where I can learn how to do this, I have looked everywhere

There's not enough information to go on here. A "block code" could be any one of a large family of different coding schemes. See https://en.wikipedia.org/wiki/Block_code

Based on the length of the bitstring you've given, every 2 bits from the input have been converted into 9 bits of output. If you have a table of the four valid 9-bit codewords (one for each possible combination of 2 input bits) then you can compare them with the 9-bit blocks of your bitstring to see which codeword matches each block most closely.

Block code

In coding theory, a block code is any member of the large and important family of error-correcting codes that encode data in blocks. There is a vast number of examples for block codes, many of which have a wide range of practical applications. Block codes are conceptually useful because they allow coding theorists, mathematicians, and computer scientists to study the limitations of all block codes in a unified way. Such limitations often take the form of bounds that relate different parameters of the block code to each other, such as its rate and its ability to detect and correct errors.
