摘要： The present invention provides a versatile system for optimizing data fragmentation in a digital communications—particularly OFDM communications—system. A digital transmission system (100) is provided, having a PHY-level constraint. An array (104, 112) of data transmission parameters (106-110, 114-116), relating to the digital transmission system, is provided. A fragmentation construct (102) is provided, and adapted to determine a number of symbols required to transmit a given data transmission payload. The fragmentation construct calculates (118), based on the number symbols required, and on certain parameter information from the array, a number of bytes of data that must be transmitted in the given data transmission payload in order to minimize pad bits added to the data transmission payload.

摘要： This specification describes several improvements to the Multiband OFDM (MB-OFDM) Physical Layer. A new PLCP frame format that better supports interoperability between 3-band and 7-band modes is described. An expanded PHY header is described with more reserved bits for future enhancements, an even number of OFDM symbols for the PLCP header that better supports time spreading and that the information is limited to just 2 OFDM symbols. A zero prefix is used to eliminate ripe in the transmitted spectrum so there is no back off required at the transmitter. A length 160 hierarchical sequence for the packet synchronization sequence is used to help eliminate the artificial side-lobe that is created during the correlation process at the receiver with the current length 128 hierarchical packet synchronization sequence.

摘要： The present invention provides a versatile system for selectively altering or shaping transmission signals in an ultra-wideband communications system (100). The system provides a serial to parallel conversion function (102) with a serial data input (116). The serial to parallel conversion function converts the serial data and outputs it in parallel format. An adjustment function (104) receives the now parallel data and selectively alters the parallel data responsive to some code or vector (118). A frequency-to-time-domain conversion function (106) receives the selectively altered parallel data and transmits it to a parallel-to-serial conversion function 108. The now serial data transfer through an OFDM prefix/suffix function 110 and a digital-to-analog conversion function 112, to an up conversion mixer function 114. Encoded digital data bits are input, converted to parallel format, and passed to the spectrum adjustment function, which provides selective adjustment of specific data units (i.e., specific OFDM sub-carriers or tones).
