<p>In order to reduce the effect of intersymbol interference in a wireless system, data are transmitted using at least two transmission formats simultaneously. For instance, the same data may be transmitted using a TDM scheme, based on QPSK, and using multicarrier modulation. At the receiver, each scheme is separately demodulated, and then combined, using, for example, maximal ratio combining. <IMAGE></p> |
