Patent number: 11962816Abstract: A novel, pervasive approach to disseminating live streaming content combines secure distributed systems, WiFi multicast, erasure coding, source coding and opportunistic offloading using hyperlocal mobile edge clouds. The solution disclosed to the technical problem of disseminating live streaming content without requiring a substantial equipment, planning and deployment of appropriate network infrastructure points offers an 11 fold reduction on the infrastructural WiFi bandwidth usage without having to modify any existing software or firmware stacks while ensuring stream integrity, authorization and authentication.Type: GrantFiled: June 18, 2020Date of Patent: April 16, 2024Assignees: UNIVERSIDADE DO PORTO, INESC TEC—INSTITUTO DE ENGENHARIA DE SISTEMAS E COMPUTADORES, TECNOLOGIA E CIÊNCIAInventors: Rolando Da Silva Martins, Luís Filipe Coelho Antunes, Manuel Eduardo Carvalho Duarte Correia, Fernando Manuel Augusto Da Silva

Patent number: 11374733Abstract: A synchronisation symbol detector that comprises two correlation modules and a comparison module. The first correlation module performs one or more correlations between the input signal and a down-converted version of the input signal and generates a first correlation metric from the one or more first correlations. The second correlation module performs one or more second correlations between the input signal and an up-converted version of the input signal and generates a second correlation metric from the one or more second correlations. The comparison module is configured to compare the first correlation metric and the second correlation metric and determine whether the input signal comprises a synchronisation symbol based on the comparison.Type: GrantFiled: March 16, 2021Date of Patent: June 28, 2022Assignee: Imagination Technologies LimitedInventors: Filipe Carvalho, Taku Yamagata

Patent number: 11184110Abstract: Channel state information (CSI) scaling modules for use in a demodulator configured to demodulate a signal received over a transmission channel, the demodulator comprising a soft decision error corrector (e.g. LDPC decoder) configured to decode data carried on data symbols of the received signal based on CSI values. The CSI scaling module is configured to monitor the performance of the soft decision error corrector and in response to determining the performance of the soft decision error corrector is below a predetermined level, dynamically select a new CSI scaling factor based on the performance of the soft decision error corrector.Type: GrantFiled: November 2, 2020Date of Patent: November 23, 2021Assignee: Imagination Technologies LimitedInventors: Filipe Carvalho, Paul Murrin
