Abstract

Wireline devices are in close proximity to wireless devices, which causes electromagnetic interference (EMI) to degrade the signal quality of wireless communications. Most of literatures dealing with this problem take actions on suppressing the coupling paths, such as low-radiation structures. In this paper, a novel source-control method is proposed which reduces the power spectrum of the source signal and thus the unintentional radiation by careful insertion of control symbols in 8b/10b, at the cost of throughput reduction. According to the reduction level, one parameter can be tuned properly to achieve the desired performance. In addition, the proposed control strategy is easy to integrate and scale with silicon process nodes due to its digital nature.
