Abstract
A method for processing signals transmitted via a connection and received by a digital interface, where individual data frames are transmitted by the signals as a sequence of modulated symbols, and where the received signals are corrected by an equalizer; the equalizer sampling the received signals, and an adaptation of the equalizer only taking place in particular time intervals in a manner controlled by a protocol.
Claims15
A method for processing signals transmitted via a connection and received by a digital interface, the method comprising:
- transmitting individual data frames by the signals as a sequence of Manchester-encoded modulated symbols;
- and
- correcting at least some of the received signals with a fractionally-spaced equalizer;
- wherein:
- an adaptation of the fractionally-spaced equalizer is performed only in particular time intervals in a manner controlled by a protocol;
- and
- the fractionally-spaced equalizer uses at least two sampling values per Manchester half-symbol.
A digital interface for processing signals, which are transmitted via a connection, comprising:
- a connection arrangement for receiving the signals, wherein individual data frames are transmitted by the signals as a sequence of Manchester-encoded modulated symbols;
- and
- a fractionally-spaced equalizer configured to sample and correct the received signals;
- wherein:
- an adaptation of the fractionally-spaced equalizer is performed only in particular time intervals in a manner controlled by a protocol;
- and
- the fractionally-spaced equalizer uses at least two sampling values per Manchester half-symbol.
A method for processing signals transmitted by a control unit via a connection and received by a digital interface at at least one peripheral unit, the method comprising:
- transmitting individual data frames by the signals as a sequence of modulated symbols in an asynchronous mode via a point-to-point connection;
- transmitting sync pulses to regulate timing of the individual data frames in a synchronous mode via a bus connection;
- and
- correcting received signals with a fractionally-spaced equalizer;
- wherein the digital interface conforms to a vehicle bus standard.
