该设置是长度为N的矢量值代码的设置。该设置的背景是我们构造了新的复值恒幅零自相关码(OFF DC)-CAZAC，其用作具有规定模糊函数行为的相位编码波形的系数。矢量值CAZAC与矢量传感器和MIMO技术相关。目标是定义离散向量值模糊函数。我们的框架乘法概念允许我们做出这个定义。发展了这种模糊函数的理论和相关性，包括从接收到的离散向量值模糊函数数据计算代码。
The setting is that of vector-valued codes of length N. The background for this setting is our construction of new complex valued constant amplitude zero autocorrelation codes (off dc) - CAZACs, which serve as coefficients for phase coded waveforms with prescribed ambiguity function behavior. Vector-valued CAZACs are relevant in light of vector sensor and MIMO technologies. The goal is to define the discrete vector-valued ambiguity function. Our notion of frame multiplication allows us to make this definition. The theory and relevance of such ambiguity functions is developed, including computation of code from received discrete vector-valued ambiguity function data.
