    Abstract: A method for emulating signal impairments to enable dynamic evaluation of transmit and receive modem performance through the use of computer-generated models enabling both an evaluation of system performance as well as a comparison of results obtained from system designs respectively exposed to both impaired and unimpaired conditions to enable direct comparison as well as comparison with standardized measurement values to facilitate system design activities prior to any hardware implementation.

    Abstract: A hybrid serial/parallel bus interface for a user equipment (UE) has a data block demultiplexing device (40). The data block demultiplexing device has an input configured to receive a data block and demultiplexes the data block into a plurality of nibbles. For each nibble, a parallel to serial converter (42) converts the nibble into serial data. A line (44) transfers each nibble's serial data. A serial to parallel converter (46) converts each nibble's serial data to recover that nibble. A data block reconstruction device (48) combines the recovered nibbles into the data block.
