As a spectral-efficiency technique for unequal error protection (UEP), hierarchical
modulation (HM) bit-interleaved coded modulation (BICM) with iterative decoding (ID) has …

Much attention had been devoted to study the bit error rate (BER) of hierarchical modulation
on point-to-point transmissions in recent years. But few mention the error performance of …

Hierarchical modulation (HM), which is also known as layered modulation, has been widely
adopted across the telecommunication industry. Its strict backward compatibility with single …

This work studies the transceiver design and convergence performance analysis for the
hierarchical modulation (HM) systems with protograph-based low-density parity-check (P …

Colour-shift keying (CSK) constitutes an important modulation scheme conceived for the
visible light communications (VLC). The signal constellation of CSK relies on three different …
