Coded modulation using I-path and Q-path interleaving and optimized rotation

摘要

The present invention represents a source signal relates to a method of transmitting a signal for which transmission on a transmission channel is planned. The method selects a first stage projection mapping to the components I and Q to determine one or more ranges of angle values ​​to approach the Gray mapping, at least one value from one or more ranges the following second phase the angle having a value defined by the rotation applied to the modulation constellation and providing the mapping of the projection of the constellation after rotation, known as the projection mapping, one component I to or comprising a step of applying the interleaving for the other components of the Q. .FIELD 8
