Group B (ϵ l  = 0, G = I, H = I) | Principle and drawbacks |
---|---|
MCS | Principle: multiple streams for selection |
Drawback: overhead (spectrum efficiency loss) | |
CE | Principle: constellation expansion |
Drawback: enlarged transmit power (BER performance degradation) | |
N-continuous | Principle: continuous signal and derivatives of signal |
Drawback: iterative decoder |
