Sentence examples for modulation the symbol from inspiring English sources

In order to maximize spectral efficiency of the offset QAM OQAMmodulationion, the symbol period T is halved.

After QPSK modulation, the symbol is of size N. Assume N c is the length of GI.

With QPSK modulation the symbol level limiter also clearly decreases the spectral re-growth and improves the spectral efficiency performance via higher average transmitted power.

The radios use BPSK modulation, hence the symbol error rate,, is given as.

After bit-to-symbol mapping, the modulation transforms the symbol stream into an analog signal suitable to be sent through the transmission channel which can degrade the signal quality.

The expression of the moment can be understood this way: given a particular type of modulation, do the symbol variables elevated to the power (with optional conjugation specified by the operator ) gives a constant result?

For an RCPC code with rate R, using the additive white Gaussian noise (AWGN) channel, binary phase shift keying (BPSK) modulation, and the symbol to noise power ratio E S N 0 = R E b N 0, the value of P d (using soft Viterbi decoding) is given by [14] P d = 1 2 erfc d E S N 0 = Q 2 d E S N 0, (4).

For a rectangular 4 m -QAM modulation, the transmit symbols belong to the set S = 1 M s a + b i ; a − b i ; − a + b i ; − a − b i, (28).

Modulation of the symbols dk,m with the synthesis filter bank results in the time-discrete output signal s [ nT s ] = ∑ m ∑ k ∈ K u θ k, m d k, m p [ nT s − mT / 2 ] e j 2 π T k nT s (1).

For a minimum double-sided signal bandwidth equal to the Nyquist frequency, where is the modulation symbol period, the Nyquist condition yields a unique solution with its time representation being a sinc pulse.

where is the modulation value of the symbol mapped into the subcarrier and is the transmitted power of the interference signal.
