Abstract
A method of communicating over a wideband communication channel divided into a plurality of sub-channels comprises dividing a single serial message intended for one of the plurality of communication devices into a plurality of parallel messages, encoding each of the plurality of parallel messages onto at least some of the plurality of sub-channels, and transmitting the encoded plurality of parallel messages to the communication device over the wideband communication channel.
Claims40
A radio transmitter module configured to generate a modulated signal having a three-level signal constellation from a data stream comprising a plurality of symbols, each symbol having one of three symbol values, the transmitter, comprising:
- a first pulser configured for generating a high signal for each of the plurality of symbols having a first symbol value and a low signal for each of the plurality of symbols having a second symbol value or a third symbol value;
- a second pulser configured for generating a high signal for each of the plurality of symbols having the third symbol value and a low signal for each of the plurality of symbols having the second symbol value or the first symbol value, the second pulser further comprising an inverted output;
- and
- a combiner coupled to the first pulser and the second pulser for combining pulsed signal outputs to generate the modulated signal.
A transmitter configured for receiving a data stream from a baseband circuit and generating a modulated signal having a three-level signal constellation, the transmitter comprising:
- a first pulser configured for generating a high signal for each of the plurality of symbols having a first symbol value and a low signal for each of the plurality of symbols having a second symbol value or a third symbol value;
- a second pulser configured for generating a high signal for each of the plurality of symbols having the third symbol value and a low signal for each of the plurality of symbols having the second symbol value or the first symbol value;
- and
- a first combiner coupled to the first pulser and the second pulser for subtracting a pulsed signal output of the second pulser from a pulsed signal output of the first pulser to generate the modulated signal.
A method of transmitting data in a wireless communication network, comprising:
- generating a high signal for each of the plurality of symbols having a first symbol value and a low signal for each of the plurality of symbols having a second symbol value or a third symbol value for producing a first pulsed signal output;
- generating a high signal for each of the plurality of symbols having the third symbol value and a low signal for each of the plurality of symbols having the second symbol value or the first symbol value for producing a second pulsed signal output;
- and
- combining the first pulsed signal output with an inverted version of the second pulsed signal output to generate at least one combined waveform having a three-level signal constellation.
