modulation efficiency造句
例句與造句
- If a forward error correction ( FEC ) code with code rate 1 / 2 is added, meaning that the encoder input bit rate is one half the encoder output rate, the spectral efficiency is 50 % of the modulation efficiency.
- If double-sideband modulation schemes such as QAM, ASK, PSK or OFDM are used, this results in a maximum symbol rate of " W " symbols / s, and in that the modulation efficiency can not exceed " N " ( bit / s ) / Hz.
- If digital single-sideband modulation is used, the passband signal with bandwidth " W " corresponds to a baseband message signal with baseband bandwidth " W ", resulting in a maximum symbol rate of 2 " W " and an attainable modulation efficiency of 2 " N " ( bit / s ) / Hz.
- An upper bound for the attainable modulation efficiency is given by the Nyquist rate or Hartley's law as follows : For a signaling alphabet with " M " alternative symbols, each symbol represents " N " = log 2 " M " bits . " N " is the modulation efficiency measured in " bit / symbol " or " bpcu ".

- It's difficult to find modulation efficiency in a sentence. 用modulation efficiency造句挺難的
