Abstract
In this paper, convolutional encoding with Viterbi decoding is applied on on-off keying (OOK) formats with different pulse shapes having different duty cycles for use in wireless infrared links at high bit rates, so as to investigate the suitability of this forwarded error correction technique to the infrared medium when different pulse shapes are employed. Here, by means of a direct application of the input-output crosscorrelation operator and the corresponding bit-error rate (BER) computation, the authors conclude that the OOK format with Gaussian pulses and low duty cycle provides quite good performance even when no channel coding is considered, obviating the need for increasing the receiver complexity.
