METHOD AND DEVICE FOR DETERMINING A SHIFTING PARAMETER TO BE USED BY A TELECOMMUNICATION DEVICE FOR TRANSFERRING SYMBOLS |
摘要 |
<p>The present invention concerns a method for determining a shifting parameter p to be used by a telecommunication device for mapping symbols on sub-carriers, the telecommunication device comprising at least two transmit antennas, the symbols being transferred through each antenna of the telecommunication device on at least an even number K , strictly greater than two, of sub-carriers allocated to the telecommunication device. The telecommunication device transfers on a first antenna on each sub-carrier ' k ', a signal representing a symbol ' X k ' in the frequency domain. The telecommunication device transferring on a second antenna on each sub-carrier ' k ', a signal representing a symbol ' X' k ' derived from the signal transferred on the first transmit antenna, for each frequency k, by the formula X¹ k sec ondant = µ �¢ - 1 k + 1 �¢ X p - 1 - k �¢ mod �¢ K * . Sub-carriers grouped in at least two clusters are allocated to the telecommunication device, and the shifting parameter p is even and determined according to clusters of sub-carriers allocated to the telecommunication device.</p> |
