MIMO precoding for filter bank modulation systems based on PSVD [PDF]
In this paper we consider the design of a linearly precoded MIMO transceiver based on filter bank (FB) modulation for transmission over broadband frequency selective fading channels.

Modulation techniques for data superposition on amplitude-modulated signals [PDF]
Double-sideband amplitude-modulation is widely used because of its simplicity in transmission and reception, but in a number of applications the inclusion of a data channel has become an additional requirement.

Spectral characterisation of the dicode PPM format [PDF]
Dicode pulse position modulation (PPM) is a new modulation format that offers improved sensitivity over digital PPM but at a reduced line-rate. This Letter considers, for the first time, the spectral characterisation of the dicode PPM modulation format ...
