Webieee802.16标准和dvb-s2标准编码算法和ber性能比较,肖扬,,ldpc码已被ieee802.16e标准和dvb-s2标准的信道编码所采纳,但是这两个标准采用了不同的编码算法使其在ber性能上有很大差异。 WebOnline CRC Calculation. Be careful: there are several ways to realize a CRC. They differ (at least) in the way which bit is shifted in first and also in the initialization of the flipflops. Enter your CRC polynomial as bit sequence ("100110001") here: This gives the following CRC polynomial (press RETURN to update): P (x) = x8+ x5+ x4+ x0.
