The future development of quantum computing threatens a host of modern cryptographic security efforts, and thus presents a new security threat to wireless communications systems. Encryption algorithms for aeronautical mobile telemetry (AMT) may …
This paper studies combine-then-equalize and equalize-then-combine receiver architectures in a multicarrier scenario motivated by 5G cellular systems. The BER performance of these two receiver architectures with polarization diversity is compared. …
The outputs of a cross-polarized antenna can produce a pair of different parallel frequency-selective channels. The optimum combining strategy is derived from maximum likelihood principles and used to define an equivalent discrete-time model. The …
Providing RHCP and LHCP outputs from the antennas vertical (V) and horizontal (H) dipoles in the resonant cavity within the antenna feeds is the current practice of ground-based station receivers in aeronautical telemetry. The equalizers on the …
16APSK is a candidate modulation for aeronautical telemetry because it has better spectral efficiency than SOQPSK-TG, but requires a linear RF power amplifier. This paper investigates the BER performance of filter-based equalizers for 16APSK …
The symmetric information rate is used to define the relationship between the APSK constellation parameters, the code rate, and the average and peak Eb/N0 . Minimizing the average Eb/N0 reproduces the DVB-S2 constellation parameters for 16- and …
