There Are Not Non-obvious Cyclic Affine-invariant Codes
We show that an affine-invariant code C of length pm is not permutation equivalent to a cyclic code except in the obvious cases: m = 1 or C is either {0}, the repetition code or it...

Four Transmit Diversity Schemes for Coded OFDM Systems with Four Transmit Antennas
We compare four open-loop transmit diversity schemes in a coded Orthogonal Frequency Division Multiplexing (OFDM) system with four transmit antennas, namely cyclic shift diversity ...
