Abstract
The present disclosure provides a transmission method comprising splitting a block of bits to be transmitted into a number of groups each consisting of k+2q bits, wherein k and q are natural numbers and each of the groups includes a subgroup consisting of k bits and two subgroups each consisting of q bits and performing 2q-ary QAM modulation on the subgroups of q bits from the groups of k+2q bits to obtain QAM symbols, respectively. The QAM symbols are processed so that two QAM symbols obtained from the two subgroups of q bits in each of the groups of k+2q bits are mapped onto at least two antennas as consecutive processed symbols. Through the use of 2k-ary FSK modulation, a frequency tone to which the two consecutive processed symbols are allocated is selected according to the subgroup of k bits from each of the groups of k+2q bits before transmission.
