systems can use quadrature amplitude modulation to maximize throughput. 16QAM uses a 16-point constellation to send four bits per symbol, with speeds...

(400GBASE-ZR) Dual polarization 16-state quadrature amplitude modulation (DP-16QAM) with coherent detection is proposed. 200 Gbit/s Ethernet Define a physical...

data transmission. Supported modulation formats on the PDSCH are QPSK, 16QAM and 64QAM. The Physical Multicast Channel (PMCH) is used for broadcast transmission...

dual carrier, higher symbol rate and higher-order modulation (32QAM and 16QAM instead of 8PSK), and turbo codes to improve error correction. This results...

Thus, there is an exponential rise in the SNR requirement if one adopts a 16QAM or 64QAM; however, the spectral efficiency improves. Nyquist–Shannon sampling...

Logical Channels (MLC) 1-7 Modulations used QPSK (4 symbol constellations), 16QAM (16 symbols) Spacing between sub-carriers 1.355 kHz (5.55 MHz / 4,096 sub-carriers)...

and an attainable modulation efficiency of 2N (bit/s)/Hz. Example 3: A 16QAM modem has an alphabet size of M = 16 alternative symbols, with N = 4 bit/symbol...
