Abstract hierarchical modulation (hm), which is also known as layered modulation, has been widely adopted across the telecommunication industry. Unwanted modulation and phase jitter synchronous frame structures used at 1544, 6312, 2048, 8448 and 44 736 kbit/s hierarchical levels. Under strong line-of-sight (los) conditions, in a con- ventional spatial modulation scheme, the signal domain exhibits better error performance than the spatial.
Offset quadrature phase-shift keying (oqpsk) is a variant of phase-shift keying modulation using 4 different values of the phase to transmit. This chapter describes the essential principles behind modulation and demodulation, which weintroducedbrieﬂyinchapter10 recallthatourgoalistotransmitdataoveracommu.
