Abstract: Aspects of the present disclosure are directed to wireless communications involving successively-received messages. As may be implemented consistent with one or more aspects characterized herein, a preamble section (122) of a currently-received message (120) is used in decoding a previously-received message (110), for wireless transmissions from a wireless transmitter (102) on a wireless communications channel (101).

Abstract: A method including receiving a data subframe having a plurality of symbols, determining a location of invalid pseudo time-domain samples in the data subframe, and discarding invalid pseudo time domain samples and recovering valid pseudo time domain samples to produce an updated data subframe, and processing the updated data subframe to produce demodulated data.

Abstract: Aspects of the present disclosure are directed to use with communications that may involve repetitive communications. As may be implemented in accordance with one or more embodiments, a subset of symbols in a current data message (130/131) are used with a corresponding subset of symbols in a previous data message (120/121), to ascertain whether the current data message is a repetition of the previous data message. This may involve, for instance, generating a resemblance metric to represent semblance between a subset the data symbols of the current data message and a subset the data symbols of the previous data message (102). The resemblance metric can be used in determining whether the current data message is a repetition of the previous data message. This approach may be useful, for example, in ascertaining whether the current message is a repetition without necessarily decoding the message.

Abstract: Aspects of the present disclosure are directed to ascertaining whether data messages are repetitions of a previous data message. As may be implemented in accordance with one or more embodiments characterized herein, data packets (130/131) are received (102) and which use a first time delay relative to transmission of a previous data packet (120/121) by a different transmitter. Repetitions (110A/111A) of data packets are also received (102), and which use a second time delay relative to transmission of a previous data packet (110/111) by the same transmitter. The second time delay is less than the first time delay. The received packet is identified (102) as being a repetition of an immediately-previous data packet based on a time delay between the data packet and the immediately-previous data packet, relative to the first and second time delays.

Abstract: Various features relate to the providing Software-Resilient User Privacy within smartphones or other devices by storing and processing all pertinent values needed for user privacy—such as security keys and access attempt counters—in hardware, such as within a System-on-a-Chip (SoC) processor formed on an integrated circuit (IC). For example, an on-die ephemeral Volatile Memory (eVM) device may be employed for storing access attempt counters or other parameters used to control malicious attack countermeasures. In one example, the eVM employs static random-access memory (SRAM) formed on the die and exploits capacitive remanence to recover stored counter values even if power is disconnected, then reconnected. On-chip NVM may be used for permanent storage of other privacy values, such as a device-unique secret key that is generated locally on the device and not known to the chip vendor, the device Original Equipment Manufacturer (OEM)) or the owner/user of the device.

Output of the RNN is taken as input into a neural network to generate a value estimate for a state-action pair. A plan that includes a plurality of sequential actions for an agent is generated. The plurality of sequential actions is chosen based on at least the value estimate.
