Rate enhancement of BICM-OFDM with adaptive coding and modulation via a bisection approach

Adaptive communication is an important topic to enhance the capabilities of future communication systems. Especially in combination with Orthogonal Frequency Division Multiplexing (ODFM) bit and power loading schemes have been devised to enhance the transmit rate of communication systems. The consideration of channel coding in the optimization is an obvious requirement. In the past, though, mainly uncoded systems have been investigated allowing for further enhancements. In this paper we propose a new scheme to adapt code rate and modulation by solving the convex optimization problem based on a bisection approach in order to maximize the achievable data rate at a fixed target error rate.
