    摘要: An address generation apparatus for quadratic permutation polynomial (QPP) interleaver receives several configurable parameters and uses a plurality of QPP units to compute and outputs a plurality of interleaving addresses according to a QPP function Π(i)=(f1i+f2i2) mod k, where f1 and f2 are QPP coefficients, k is information block length of an input sequence, 0≦i≦k−1, and mod is a modulus operation. Each of the plurality of QPP units is a parallel computation unit, and outputs in parallel a corresponding group of interleaver addresses, where Π(i) is also a ith interleaving address generated by the apparatus.

    摘要: A multiplexing method for data switching is disclosed. In the method, a continuous data is received, and the continuous data includes a plurality of super frames, and each super frame includes a plurality of frames. These super frames are divided into a set of even super frames and a set of odd super frames. The frames included in the set of odd super frames are sorted by corresponding required bit error rate of each frame decreasingly or increasingly. The frames included in the set of even super frames are sorted by the required bit error rate of each frame increasingly or decreasingly. An encoder is used to encode these sorted super frames.
