Abstract :
A novel rate-adaptive transmission scheme using block coding of variable Hamming weight is presented for use in indoor optical wireless communications systems. This coding scheme is based on multiple pulse-position modulation, where codewords with different Hamming weight are allowed. The improvement in performance is corroborated by bit error rate computation using Monte Carlo simulation
