Abstract
To transmit data, a set of at least 2m n×n matrices that represent an extension of a fixed-point-free group is provided. To each of 2m of the matrices is allocated one of the binary numbers from 0 to 2m−1. The data are mapped into the matrices according to the allocation. The mapped matrices are transmitted, preferably using n antennas, one antenna per row of each matrix.
Claims12
A method of transmitting and receiving data, comprising the steps of:
- (a) providing a set of at least 2m nxn matrices that represent an extension of a fixed-point-free group, each said matrix including n2 matrix elements, where m is a positive integer and n is an integer greater than 1;
- (b) allocating each binary number between 0 and binary 2m−1 to a respective one of said matrices;
- (c) mapping the data into said matrices according to said allocating;
- and
- (d) for each said matrix into which the data are mapped, transmitting said matrix elements of said each matrix.
2 more elements
A transmitter for transmitting data, comprising:
- (a) a coder for mapping the data into a set of 2m nxn matrices obtained by providing a set of at least 2m nxn matrices that represent an extension of a fixed-point-free group and allocating each binary number between 0 and binary 2m−1 to a respective one of said at least 2m matrices, each said matrix into which the data are mapped including n2 matrix elements, m being a positive integer, n being an integer greater than 1, said mapping being according to said allocating;
- and
- (b) at least one antenna for transmitting said matrix elements.
