Quasi-Orthogonal Space-Time Block Coding Using Polynomial Phase Modulation [PDF]
, 2011 Recently, polynomial phase modulation (PPM) was shown to be a power- and bandwidth-efficient modulation format. These two characteristics are in high demand nowadays specially in mobile applications, where devices with size, weight, and power (SWaP ...

Concatenated space-time block coding with asymmetric MPSK TCM
Tongxin xuebao, 2010 The field of concatenated space-time block coding （inner） with trellis coded modulation （outer） has recently attracted interest as a means of jointly considering the error correction coding gain and diversity gain possible without bandwidth expansion and

Analysis of IEEE 802.11N-like transmission techniques with and without prior CSI for video applications [PDF]
, 2007 Previous research into MIMO systems has focused little on optimisation for video transmission. In terms of multimedia transmission, spatial multiplexing (SM) is commonly proposed as the most suitable MIMO technique.

Space-time block coding for single-carrier block transmission DS-CDMA downlink
IEEE J. Sel. Areas Commun., 2003 The combination of space-time block coding (STBC) and direct-sequence code-division multiple access (DS-CDMA) has the potential to increase the performance of multiple users in a cellular network.

Distributed convolutional-coded differential space-time block coding for cooperative communications
, 2010 A low complexity distributed coding scheme is proposed for communications over Rayleigh fading channels. Convolutional Coding (CC) assisted Differential Phase-Shift Keying (DPSK) modulation is employed at the source node for conveying the source signals ...
