Patent ID: 8077766

Claim:
Method of reception of a received data signal formed by at least one received block of symbols and representing a source signal, said method comprising: implementing an initialization phase comprising block-to-block equalization of said received signal, delivering for each block of received symbols, a block of equalized symbols each formed by one set of bits; and at least one iteration of improvement of an estimation of said received signal comprising the following steps, for a current block of equalized symbols: obtaining at least one decoded bit, by bit-to-bit decoding of a current subset of at least one bit belonging to said current block of equalized symbols; updating at least one symbol estimated during said initialization phase or updated during a previous iteration of improvement, as a function of the decoded bit or bits, delivering an updated block of estimated symbols, constituted by the decoded bit or bits and at least one bit decoded during at least one previous improvement iteration or during said initialization phase; determining an improved block of equalized symbols by cancellation of interference, taking account of said updated block of estimated symbols, said improved block of equalized symbols becoming the current block of equalized symbols of any subsequent iteration.
