Abstract
An ultra-wideband (UWB) communication system comprising a transmitter and a receiver is disclosed. In one embodiment, a symbol mapper circuit in the transmitter is adapted, in a first mode, to develop symbols having the number of pulses as currently defined in the 4z Standard; and, in a second mode, to develop symbols having fewer pulses than as currently defined in the 4z Standard. In an optional third mode, each data bit is mapped to a single pulse.
Claims22
An apparatus for higher data rate transmission, comprising:
- a transmitter operable to perform ultra-wideband (UWB) communication;
- a processor communicatively coupled to the transmitter;
- and
- a non-transitory computer readable medium including executable instructions which, when executed by the processor, causes the processor to:
- develop a first plurality of symbols at a first rate of 31.2 Mb/s, wherein each symbol in the first plurality of symbols comprises eight pulses and eight silent chips in a first mode of operation;
- and
- develop a second plurality of symbols at a second rate of 62.4 Mb/s, wherein each symbol in the second plurality of symbols comprises four pulses and four silent chips in a second mode of operation.
A method for performing an ultra-wideband (UWB) communication with a higher data rate transmission using a transmitter communicatively coupled to a processor, the method comprising:
- developing, with the processor, a first plurality of symbols at a first rate of 31.2 Mb/s, wherein each symbol in the first plurality of symbols comprises eight pulses and eight silent chips in a first mode of operation;
- and
- developing, with the processor, a second plurality of symbols at a second rate of 62.4 Mb/s, wherein each symbol in the second plurality of symbols comprises four pulses and four silent chips in a second mode of operation.
