Abstract:
The performance of on-off Keying (OOK) based wireless infrared transmission can be seriously deteriorated by the so called “transient baseline wander”, which is caused by the inherent high-pass characteristics of the receiver. The signal distortion induced by such an impairment can be mitigated by using a line code. In this paper, we propose two 8B10B line coding schemes for Gbps wireless infrared line-of-sight (LOS) transmission based on the non-return to zero (NRZ) OOK modulation: the classic IBM code and the concatenated flipped bit insertion (CFBI) code. The latter is newly designed and enables simpler and more effective encoding and decoding algorithms. Simulation results demonstrate a small susceptibility to the transient baseline wander. Both codes are DC-balanced and offer regular state transitions.
