Autocorrelation-Gold
Spread spectrum merupakan sistem dimana sinyal yang dikirimkan memiliki bandwidth yang jauh lebih lebar daripada bandwidth sinyal informasinya sendiri. Proses pelebaran bandwidth sinyal informasi ini dilakukan pada sisi pengirim dan disebut spreading. Sebaliknya, proses penyempitan kembali bandwidth sinyal informasi dilakukan di sisi penerima, dan disebut despreading. Pada gambar 1 berikut menunjukkan proses yang terjadi pada sistem spread spectrum.

OFDM
RA准则下的OFDM自适应资源分配问题,涉及载波和功率的分配,是一个既含有离散决策变量,又含有连续决策变量的非线性优化模型,且含有较为复杂的非线性约束,因此适合采用智能优化算法进行求解。(RA OFDM under guideline adaptive resource allocation problem, involving carrier and power allocation is a decision with both a discrete variable, but also with continuous decision variables of nonlinear optimization models, and contains more complex nonlinear constraints, so for using intelligent optimization algorithm.)
