A power line channel estimation mechanism based on compressed sensing
Through the analysis of power line channel characteristics
the corresponding mathematical model was established
the multipath channel characteristics of power line were studied.Combined with a novel compressed sensing and processing technology
a channel estimation method of power line based on compressed sensing was proposed.The transmission characteristics of power line channel were analyzed.Taking advantage of its sparse
only a small amount of noise and channel parameters needed to be collected
extracted and stored
which greatly reduced the digital signal processing module of data processing
and the storage hardware requirements and hardware costs were reduced.
