Detailed Description

template<class T>
class itpp::Block_Interleaver< T >

Block Interleaver Class.

Data is written row-wise and read column-wise when interleaving.

Example of use:

    BPSK bpsk;
    bvec bits = "0 1 1 0 0 0 1 1 1 1 0 0 1 0 0 1";
    vec symbols = bpsk.modulate_bits(bits);

    Block_Interleaver<double> block_interleaver(4,4);
    vec interleaved_symbols = block_interleaver.interleave(symbols);
