ABSTRACT:
A bit error probability (BEP) estimation method includes de-shaping a coded block to obtain a channel hard output block comprising a header hard output and at least one data hard output, de-puncturing and decoding the header hard output to obtain a decoded header part, determining whether the decoded header part has errors, selecting the decoded header part or a decoded whole block as a selected part based on the determination result, wherein the decoded whole block comprises the decoded header part and a decoded data part obtained by de-puncturing and decoding the data hard output, re-encoding the selected part to obtain a re-encoded decision, and comparing the re-encoded decision to the header hard output or the channel hard output corresponding to the selected part to obtain the BEP of the coded block. A receiver employing the BEP estimation method is also provided in the invention.
