... a OFDM case comparing to the MIMO scenario. 2.5. Crystallized Rate Regions and Time-Sharing Coefficients for the MIMO Transmission. The idea of the crystallized rate regions has been introduced ... conclusions can be drawn for the MIMO case. We will then discuss various achievable rate regions for the interference MIMO channel. We will analyze the properties of the...

(3) A single-layer system using either uniform QPSK or uniform 8-PSK ... Ksps. For a single-layer system, if uniform QPSK is used as mod- ulation, the message bitrate (after channel coding) is r s+c = 256 Kbps; if uniform 8-PSK is used as modulation, r s+c = 384 K...
