VWDK,a new data modulation technique with high band efficiency is introduced.Using this technique,the frequency band needed for data transmission can be greatly compacted without loss of SNR.The theory of VWDK is explained and the simulation results are also presented.The band efficiency of VWDK is estimated and the design proposal for the VWDK transmission system is indicated.

Key words: VWDK;band efficiency;Power spectrum;Modem
