Abstract
A communications system comprises a transmitter, receiver and channel. The transmitter transmits multiple copies of each data bit in a multi-dimension modulation scheme matrix, the dimensions being selected from frequency, time and code. Each dimension is divided into sub-groups. A bit-loading method is used such that copies of each data bit (b11, b12, b13) are allocated within the matrix according to a predetermined arrangement so that within each dimension copies of the same data bit reside within different sub-groups.
