A new algorithm of physical layer resource allocation for broadband power line carrier communication
Broadband power line carrier communication adopts OFDM technology to effectively improve system communication performance, and provides abundant communication resource guarantee for realizing broadband power line communication power multi-service applications. Aiming at the problem of broadband power line carrier communication resource allocation, this paper proposes a low-complexity physical layer resource allocation algorithm. First, based on the equal power allocation method, the set of subcarriers required by each user to meet their minimum rate requirements is determined, and the multi-user resource allocation problem is reduced to a single-user resource allocation problem, and then the power of the sub-carrier set allocated by each user is optimized to further improve the system throughput. Experiments show that the algorithm in this paper effectively improves the network throughput while meeting the minimum transmission rate requirements of more users" concurrent services.
