Patent ID: 8290018

Claim:
A method for transmitting data in a telecommunication system that includes at least a first transceiver and a second transceiver linked together by means of at least one communication channel, at least one of the transceivers being mobile, the method comprising: spreading said data over a plurality of components; and an equalization step of multiplying each of the components resulting from the spreading step by a corresponding predetermined equalization value representative of communication conditions within the communication channel, wherein at least one predetermined equalization value is determined so as to account for a Doppler effect resulting from a movement of the mobile transceiver, which adversely affects the communication conditions within the communication channel, wherein each predetermined equalization value is calculated using an equation that includes a parameter representative of a noise level in said communication channel and an additional noise variance representative of said Doppler effect; and the additional noise variance representative of said Doppler effect increases with an amount of time elapsed since an incoming signal has been received by the mobile transceiver.
