A system comprises a receiver comprising a first pseudorandom binary sequence module, and a transmitter comprising a second pseudorandom binary sequence module. The first pseudorandom binary sequence module is initialized with a first received bit sequence to start bit sequence generation with the aid of the second pseudorandom binary sequence module. Further, received remaining bits are compared to bit sequences generated with the aid of the first pseudorandom binary sequence module to determine whether a bit error rate is below a predefined threshold.
