Abstract: Disclosed in some examples are systems, methods, devices, and machine-readable mediums for improved communications between a software-defined radio front-end device and a network-based computing device. Rather than packetize samples together, same bit positions from multiple ADC samples may be packetized together. If a Quality of Service (QoS) metric of the network connection between the RF front-end device and the network-based processing computing drops below a threshold, the RF front-end device may prioritize sending packets with the more significant bits over packets with less significant bits. In other examples, the RF front-end device may prioritize samples corresponding to certain data types over other data types.

Abstract: Assigning an appropriate modulation profile for an orthogonal frequency-division multiplexing (OFDM) channel. The current modulation profile assigned to a specific OFDM modem for communicating over a specific OFDM channel is examined to determine whether to consider reassigning the specific OFDM modem to a different modulation profile. Only upon determining consideration should be given, an assessment is made as to which modulation profile, of a set of candidate modulation profiles available to that OFDM modem for communicating over the specific OFDM channel, should be assigned to the specific OFDM modem using linear domain averaging over the OFDM subcarriers of the ratios between a Mean Error Rate (MER) threshold per subcarrier for the specific OFDM modem and the MER reported by the specific OFDM modem per subcarrier. A new modulation profile is assigned to the specific modem based on the assessment.
