Low-complexity sequence detection algorithm for FSK-based power line communications

This paper presents a novel sequence detection algorithm well-suited for data transmission and wake-up receiver addressing in FSK-based narrowband power line communication applications, where the communication channel is characterized by non-white noise, interferers and frequency-selective signal attenuation. The algorithm is discussed in detail, verified by Monte Carlo simulations and compared to state of the art solutions. Furthermore, it is shown that, in an equivalent noise scenario, the proposed algorithm offers a performance comparable to the state of the art technologies with a significantly lower algorithmic complexity.
