  1. A binary check digit ; for example, a parity bit

    一個二進制校驗位,例如奇偶位。
  2. A bit added to a binary code that indicates parity and is used to check the integrity of data

    奇偶校驗位加在二進制碼上的一個標明奇偶數的位,用於檢驗數據的完整性
  3. In detail, they are bit - interleaved coded modulation ( with iterative decoding ), low - density parity - check codes and stf technology. by the performance analysis of bicm ( - id ), which can make code and modulation optimal separately, and achieve maximum possible coding diversity as well as modulation gain, guidelines for its design and an easy algorithm for siso are proposed. design of capacity - approaching of ldpc codes and efficient encoding of them as well as several kinds of its decoding algorithms are investigated

    具體的講,就是討論了基於比特交織的編碼調制技術,並給出了映射方式的設計準則以及核心模塊siso的一種簡單的f - map演算法;研究了編碼最小漢明距隨碼長線性增加的ldpc碼的幾個方面的問題,包括接近香農限碼子集的度分佈對的設計、有效編碼器的實現和各種譯碼演算法的優缺點,並對基於ldpc碼的bicm應用於ofdm傳輸系統中的性能進行了模擬。
