The following Matlab project contains the source code and Matlab examples used for xdsl bitloading.
Bitloading in DSL technique is different from WLAN. Here, we are measuring SNR for every subchannel and based on the SNR value Bi Value is loaded.
Orthogonal frequency-division multiplexing (OFDM) is a method of encoding digital data on multiple carrier frequencies. OFDM has developed into a popular scheme for wideband digital communication, whether wireless or over copper wires, used in applications such as digital television and audio broadcasting, DSL Internet access, wireless networks, powerline networks, and 4G mobile communications.
