Abstract
A system is provided that can introduce data redundancy into wireless communications, and in particular ultra-wideband (UWB) wireless communications to increase the communication range when transmitting data that has low transmission rates. Multipath degradation, introduced by the extended communications range, can be mitigated by frequency hopping between the orthogonal frequency-division multiplexed symbols of the ultra-wideband waveform. Frequency hopping can place adjacent symbols in different frequency channels for filtering. Data redundancy can be expanded in the time domain and/or the frequency domain, resulting in extended range.
Claims14
A system comprising:
- at least one processor;
- a memory storing machine-readable instructions which, when executed by the at least one processor, cause the at least one processor to perform one or more operations, the one or more operations comprising:
- receiving, at a first set of slave nodes, a wideband signal, the first set of slave nodes comprising one or more slave nodes and being at least a first part of a wideband network, the wideband network using a wideband channel;
- measuring, at the first set of slave nodes, a signal strength of the wideband signal;
- determining, at the first set of slave nodes, a noise level for the wideband signal;
- estimating, at the first set of slave nodes, a first estimated amount of interference of the wideband signal;
- transmitting, from the first set of slave nodes and to a master node, the first estimated amount of interference;
- and
- generating, at the master node, an estimated amount of network interference by comparing the first estimated amount of interference with a second estimated amount of interference from a second set of slave nodes, the second set of slave nodes being at least a second part of the wideband network.
