| description | The invention relates to the technical field of power line communication, and discloses a code index time division multiple access method and device based on a power line channel. Power line channel transmission time is divided into a plurality of time slices, the plurality of time slices are distributed to each communication node pair, and the communication node pair comprises a sending node and a receiving node; during data transmission, a sending node generates a bit block according to a sending signal, maps the bit block into an extension code, generates an analog signal based on the extension code, and sends the generated analog signal in a distributed time slice; and each receiving node detects the signal of the power line channel in the corresponding time slice and demodulates the detected signal so as to recover the transmitted signal. The invention solves the technical problem of improving the signal-to-noise ratio and the communication rate of each node during multi-node access.
