Abstract: Over the recent decades, the emergence of advanced wireless technologies has attracted many researchers and industries to explore in the field of next generation wireless links towards capacity optimisation with minimal energy requirements. This gave beginning to a new dimension of research in the field of 'Green yet high capacity links' which can connect our physical world to the digital reality with a support from environment friendly networks. The phenomenal growth in wireless applications and technology development also demands a step up in link capacity. This paper focuses on reviewing recent concepts and methodologies to improve link capacity for the next generation wireless systems. The main aim of this paper is to provide a conceptual understanding about the impact of modulation techniques and error control codes towards capacity improvement.

Keywords: hierarchical modulation; OFDM; FBMC; LDPC; Polar codes; Turbo codes; spatial modulation.
