On the other hand, the use of 16QAM modulation would allow for a channel-coding rate in the order of one half. Similarly, if a bandwidth efficiency close to 4 information bits per modulation symbol is ...

(4) Coding rate of 4/5 The coding rate shall be set so as to exceed the transmission bit rate with 32APSK at the practical received C/N when it is applied to 64APSK. (5) Design C/N is 16 dB.

The DVB group's decision on a new coding scheme for satellite transmission could have far-reaching implications for a number of chip companies such as Broadcom, STMicroelectronics and LSI Logic. They ...

Theoretical analysis of the UBP-CM with GCS aligns well with simulation results under an additive white Gaussian noise (AWGN) channel. In the experiments, a signal-to-noise ratio (SNR) gain of 23.1 dB ...

The recently proposed affine frequency division multiplexing (AFDM) is a new transmission waveform that has shown excellent performance in high-mobility environments, making it a sensible option for ...

We suggest that multiplexing implemented through periodic modulation of firing-rate population codes enables flexible reconfiguration of effective connectivity among brain areas.

Here’s how it works. RRsat Global Communications Network and NovelSat 3G-Sat have announced that live testing of the NovelSat 3G-Sat NS3 modulation technology has resulted in a 26 percent data rate ...
