    摘要： In a MIMO delay spread (OFDM) system or a MIMO single carrier (non-OFDM) system wherein a transmitter transmits signals to a receiver through multipath fading channels, an equivalent frequency-domain MIMO multipath channel matrix is used to estimate the maximum mutual information regarding the relationship between transmitted signals and received signals. It is possible to compute the upper bound of the maximum mutual information at least based on the total energy of all resolvable paths in the fading channels. The upper bound or the changes in the upper bound can be used to adjust the transmission parameters used in data transmission. The transmission parameters include the modulation order in the modulation process, the code rate and the puncturing rate.

    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： Apparatus, and an associated method, for facilitating optimization of the communication capacity of a communication system. A selector is coupled to receive channel state information associated with the channel conditions upon subcarriers defined pursuant to an OFDM (orthogonal frequency division multiplexing) the selector operates to select communication allocation of the data to be communicated on the different ones of the subcarriers. Selection is made pursuant to a selected optimization scheme. And, bit and power profiles are formed that are utilized to control the modulation scheme by which data is modulated upon the different subcarriers. As channel conditions change, the communication allocations are adaptively altered.

    摘要： Apparatus, and associated method, for increasing the diversity levels of data communicated upon a channel susceptible to fading. Trellis-coded modulation is performed upon data to be communicated to form trellis-coded modulated and rotated symbols. Coordinate interleaving is performed by a coordinate interleaver upon selected ones of the modulated and rotated symbols. The coordinate interleaving is performed according to a selected coordinate interleaving scheme responsive to indications of channel conditions upon the communication channel. When delivered to a receiving station, a coordinate deinterleaver deinterleaves the interleaved symbols according to a coordinate deinterleaving scheme that corresponds to the coordinate interleaving scheme.
