摘要： Diversity techniques are commonly used in wireless communications to combat multi-path fading. Recent interests in ultra-wideband technology focus on multi-band OFDM systems that can explore the high diversity due to the independent frequency bands. To achieve full diversity with high data rate, a system (800), apparatus (500) and method that uses coded modulation with spreading rotation of transmitted signals. A 2×2 integer rotation matrix for QAM signals, 3×3 and 4×4 integer rotation matrices for QAM signals are provided. Compared with the non-regular QAM shape for real rotation matrices, each of these integer rotation matrices makes the regular QAM shape after rotation. The systematic design of these spreading matrices can be used to simplify the receiver structure such as simplified ML, MMSE and ZF, and then reduce their decoding complexity. Further, the present invention achieves cooperative diversity not only from distributed users but also from the signal space diversity of each user. An embodiment is provided for a cooperative system (100) in which different rows of integer rotation matrices are used by a source and relays as a modulation scheme to increase cooperative diversity.

摘要： The present invention provides a system (400), device (200, 300), and method (200) for a spatial multiplexing (SMX) transmission scheme combined with symbol spreading and rotation using a pre-determined matrix R, which can greatly improve system performance without requiring additional bandwidth or power consumption under fast Rayleigh flat fading channels or high frequency-selective channels in UWB systems. Because of the lattice-based structure, sphere decoding is employed to reduce the complexity of ML decoding while maintaining the near ML performance. On the other hand, ZF and MMSE receivers can also be used due to the systematic structure at the transmitter.

摘要： The present invention provides a system (600), device (500) and method (400) for automatic partner selection in an existing Cooperative MAC (CMAC) protocol, which uses the Ready-to-Send (RTS), Clear-to-Send (CTS) and Partner-Clear-to-Send (PCTS) handshaking to establish cooperation. The present invention enables a “best” partner/relay (500.R.k) who is also willing to cooperate to relay information to a destination (500.D.J) for the transmitting device (i.e., the source), without the source (500.S.i) making a decision on partner selection. That is, the present invention provides a new mechanism by which the best partner/relay (500.R.k) that is also willing to cooperate will “step in” automatically without the source's involvement in selection of the partner/relay (500.R.k). This mechanism is contention-based and the partner is “selected” using local information only in a fully distributed manner.
