Transactions on Emerging Telecommunications Technologies, (2016).

We investigate staircase codes, a class of high-performance forward-error-correction codes for high-rate transmission, and propose staircase codes with adaptive rates for time-variant optical wireless channels. The variable-rate staircase codes are used in a type-II hybrid automatic repeat request framework such that throughput is maximised by avoiding retransmissions of the whole staircase blocks that initially-at high code rate-may not have been decoded successfully. These rate-adaptive staircase codes employ at their core the standard Bose-Chaudhuri-Hochquenghem component codes, but they are concatenated with Reed-Solomon codes as extra components to implement burst-error correction and rate-adaptivity. Bit error performance and throughput of the rate-adaptive staircase codes are investigated by analysis and confirmed with simulation.
