A wheel rim processing machine which includes an oscillating table rotation base. Said mass is suitable for producing layers that are self-supporting or that are placed on a substrate from which or with which composite layers with electrochemical properties can be produced, such as accumulators, batteries, condensators, solar cells and electrochromic indicating elements. The print job is sent from a computing device associated with a user. The digital processing can include a bandpass transfer function and a lowpass transfer function. The method includes receiving signals in a same frequency band from Base Stations included in a CoMP set, which operate in joint processing mode, selecting a first precoding matrix for each of the BSs using the received signals, generating a second precoding matrix by combining the first precoding matrices, and transmitting an index of the second precoding matrix to a serving BS among the BSs. A second plurality of trenches in the termination region.
