Abstract
Systems and methods for reduced interpath interference for ultrawideband (UWB) wireless communication are disclosed. In one aspect, a wireless communication device employs a systematic and non-random pulse-hopping scheme to introduce variable distances between pulses to reduce collision rates from interpath interference. In exemplary aspects, the scheme optimizes avoidance of collision rates for distances between paths of up to thirty nanoseconds (30 ns). The use of an optimized grid will be stable regardless of position of the user, thereby avoiding transmission drops and improving the user experience.
Claims19
A transceiver comprising:
- a transmitter circuit configured to transmit a wireless signal through an antenna;
- and
- a control circuit coupled to the transmitter circuit, the control circuit configured to:
- apply a systematic and non-random pulse-hopping pattern to a symbol to be transmitted.
A mobile computing device comprising:
- an antenna;
- and
- a transceiver comprising:
- receive circuitry;
- transmit circuitry configured to transmit a wireless signal through the antenna;
- and
- a control circuit coupled to the transmit circuitry, the control circuit configured to:
- apply a systematic and non-random pulse-hopping pattern to a symbol to be transmitted.
A method for transmitting a wireless signal, the method comprising:
- receiving at a mobile computing device at least one systematic and non-random pulse-hopping pattern;
- applying the at least one systematic and non-random pulse-hopping pattern to a symbol to be transmitted;
- and
- transmitting the symbol to a remote device.
