The development of our digital connectivity was built on QAM, which plays a key role in cable internet, television, and old ...

An unencrypted digital channel from the cable company. Most digital TV sets have a built-in clear QAM tuner, which can decode a limited number of TV stations, such as local broadcasts, PBS and ...

Full digital demodulator supports 8-VSB and 64/256-QAM. Fully separable core for optional OOB forward data channel. Prototyped in FPGA and tested in the lab and in the field by independent ...

This is a high throughput QAM constellation demapper and Log Likelihood Ratio (LLR) bit-metric generator. The core is capable of accepting a new equalised QAM symbol per clock cycle and generates all ...

Varying the voltage of a carrier or a direct current in order to transmit analog or digital data. Amplitude modulation (AM) is the oldest method of transmitting human voice electronically.

At present, a cable TV network receives digital broadcasting through antennas ... a single channel (6 MHz bandwidth) using either 64-QAM *1 or 256-QAM carrier waves. Because the transmission ...
