To support the frame sync block in BPSK, QPSK mode -- the timing recovery block tracks sample offset and decimates the input stream by sampling every Nth symbol. The timing is tracked using zero crossing or peaks. We will build phase tracking into this block as well, like costas loop. The block should support a resync label to indicate the start of a new frame and to reset timing offsets. In the case of phase recovery, this label can indicate the initial phase error when label.data is provided
