Examples are disclosed for transmitting and receiving schemes for multiuser single-carrier space time spreading with frequency domain equalization. In one embodiment, the LS frequency is set to a value of 832 MHz, thus preventing simultaneously desensitization of the GSM band and also the GPS band. The projection defines a retaining slot opened sideward and a supporting portion disposed between the retaining slot and the rear face of the housing, a connecting portion of the central contact climbs over the supporting portion and runs through the retaining slot. A buffer, when adjusted by a buffer value, causes the first in-content reference to be encountered at a coordinated time during playback by the first media processor, which results in a synchronized playback of the streaming media between the first and second media processors. The separating discs are preferably given a pre-tension, and the abutment faces are then shaped correspondingly having a slightly convex shape.
