Abstract
A method is provided for convolutive coding for the transmission of space-time block codes according to the technique termed Golden Code, in a wireless communication network comprising at least a plurality of transmit antennas. The Golden Code coding is associated with a trellis coded modulation, and the necessary partitioning to the trellis is produced such that, for each partitioning step, a set Γ∞ is multiplied by at least one element β from the set Bk (k>1) of elements of Az such that: Bk={X∈Az and |Det(X)|2=2k}, the set Γ∞, termed “infinite Golden Code”, being a principal ideal of the ring Az as defined by the Golden Code technique.

A method of convolutive coding for the transmission of space-time block codes according to the technique termed Golden Code, the transmission being provided over a wireless communication network including at least a plurality of transmit antennas, comprising:
- producing a necessary partition of a trellis coded modulation TCM using a coder for coding the Golden Code, such that, for each partitioning step, a set Γ∞ is multiplied by at least one element β from the set Bk (k>1) of elements of Az such that:
- Bk={X∈Az and |Det(X)|2=2k},
- wherein the set Γ∞ termed “infinite Golden Code” is a principal ideal of the ring Az as defined by the Golden Code technique.
A system for transmitting coded bits, comprising:
- a wireless communication network including at least a plurality of transmit antennas;
- a convolutive coder configured for receiving a set of non-coded bits, generating a set of coded bits, and transmitting said set of coded bits across the wireless communication network;
- and
- a space-time block coder of a Golden Code type, which converts said set of non-coded bits to said set of coded bits by producing a necessary partition of a trellis coded modulation TCM, such that, for each partitioning step, a set Γ∞ is multiplied by at least one element β from the set Bk (k>1) of elements of Az such that:
- Bk={X∈Az and |Det(X)|2=2k},
- wherein the set Γ∞ termed “infinite Golden Code” is a principal ideal of the ring Az as defined by the Golden Code technique.
