Claim Text:
1. A method for transmitting data via a power-line network, the method comprising: receiving data bits to be transmitted; loading multiple copies of the data bits in a multi-dimension modulation scheme matrix, the dimensions being selected from frequency, time and code, each dimension being divided into sub-groups, allocating copies of each data bit within the matrix according to a predetermined arrangement so that within each dimension copies of the same data bit reside within different sub-groups; wherein within each dimension the predetermined arrangement specifies positions of the copies of the data bits, such that the position of each successive copy of a respective data bit is specified according to a progression with respect to the position of the preceding copy of that data bit; wherein the progression for one or more of the dimensions is based on an arithmetic function, and wherein for one or more of the dimensions, the number of sub-groups between successive copies of a respective data bit varies across the matrix; modulating a signal in accordance with the modulation scheme matrix; and transmitting the signal via a mains power line.
