We consider a general burst block orthogonal space- time coded CPM modulation in MIMO slowly fading Rayleigh channel. The modulated signal has multidimensional constellation waveforms. The optimal receiver must perform a multidimensional matched filtering on its front-end. This operation is highly demanding on the processing computational resources. We derive sub-optimal complexity reducing receiver...
A constant envelope continuous phase modulation (CPM) class of Multi-Channel (MC) modulations for multi-antenna transmitters is considered. Each receive antenna receives a superposition of CPM waveforms. The useful signal at the receiver spans a curved space - the information waveform manifold (IWM). Particularly it has the form of a cylinder on a cylinder for 2-component CPM signals. At the receiver,...
The authors assume burst Alamouti coded STC CPM (MSK) modulation in MIMO channel as a particular example of nonlinear multichannel modulation (NMM). The NMM has multidimensional constellation waveforms. The major goal is to find suboptimal receiver signal preprocessing that could substantially reduce receiver decoding metric computation complexity with minor degradation of the STC performance. The...
