- Abstract
- Hierarchical modulation provides unequal error protection to transmitted data according to their relative importance. In this article, hierarchical modulation constellation based on circular theta-quadrature amplitude modulation (CTQAM), 4/M-CTQAM, M = 2(k), k >= 4, is proposed. We provide a construction method and bit-to-symbol mapping for the proposed hierarchical modulation constellation. We then examine the bit error rate performance of 4/M-CTQAM and validate the theoretical results through computer simulations in additive white Gaussian noise (AWGN) and Rayleigh fading channels.
