摘要： Apparatus, and an associated method, for facilitating communication of communication data upon a communication channel susceptible to distortion. Both diversity techniques and spatial multiplexing techniques are utilized to compensate for the distortion introduced upon the data during its communication. Separate parts of the communication data are mapped pursuant to separate mapping schemes. The mapping schemes are selected to exhibit different properties. When the communication data is communicated upon the communication channel and delivered to a receiving station, a decoder decodes the data to recover the informational content of the data.

摘要： An M-ary signal constellation within an N-dimensional space is defined, preferably such that each of the M symbols reside upon the surface of an N-dimensional sphere and such that a minimum distance between symbols is maximized. N orthogonal functions are used as the bases for representing the N-dimensional symbols for transmission. Orthogonal functions exhibiting orthogonality in frequency, time and/or space are also described for this purpose. Furthermore, conventional QAM symbol encoding may be used to represent the N-dimensional symbols, thereby facilitating the use of conventional modulation techniques. In this manner, higher dimensional modulation schemes may be realized.
摘要翻译：定义N维空间内的M元信号星座，优选地使得M个符号中的每一个驻留在N维球体的表面上，并且使得符号之间的最小距离最大化。 N个正交函数用作表示用于传输的N维符号的基础。为此也描述了在频率，时间和/或空间中呈现正交性的正交函数。此外，常规QAM符号编码可以用于表示N维符号，从而有助于使用常规调制技术。以这种方式，可以实现更高维度的调制方案。
