CA 2206581

The encoding/transmission of information in an OFDM system is enhanced by using complementary codes. The complementary codes, more particularly, are converted into phase vectors and the resulting phase vectors are then used to modulate respective carrier signals. The modulated result is then transmitted to a receiver which decodes the received signals to recover the encoded information.

L'invention est une méthode d'amélioration du codage et de la transmission d'information dans un système OFDM par l'utilisation de codes complémentaires. Ceux-ci sont convertis en vecteurs de phase qui sont utilisés pour moduler des porteuses individuelles. Les porteuses modulées sont ensuite transmises à un récepteur qui les décode pour recouvrer l'information codée.
