摘要： Variable length codewords are grouped into successive N bit word groups (25) in sequential order as received from a variable length codeword encoder (18). The N-bit groups are each stored in corresponding N-bit-wide memory locations in a buffer memory (30) prior to transmission over a channel (16). The locations are filled to capacity on one clock pulse and emptied on a second clock pulse to efficiently utilize the memory at a given clock rate.

摘要： A radio wave data transmission apparatus comprises a plurality of switches (2), a data converter (14) and a transmission section (15). The switches (2) are selectively activated by a finger tip being moved as if to write a character, thereby providing data showing a character. The data converter (14) converts this data into radio wave signals. These signals are transmitted from a transmission section (15).

摘要： A two-dimensional optimization between adaptive modulation and coding (AMC) and multi-code transmission targets the best bit rate at which a highest useable modulation and coding scheme (MCS) achieves a maximum allowed number of channelization codes or less. The optimized MCS and number of channelization codes at a best bit rate is communicated from a transmitter to a receiver, possibly also with power information for instance using a transport format combination indicator (TFCI). A user equipment may play the role of carrying out the optimization and signaling the result to the Node B or may instead receive the result as carried out by the Node B or RNC in response to a radio link quality measurement sent from the UE to the Node B.

摘要： An optical disk apparatus has a control portion for, based on address information and authentication information read out from an optical disk, providing access to a specific server via a communication line, thereby acquiring extensible information, and a reproducing portion for reproducing and outputting the acquired extensible information. In this optical disk apparatus, if an optical disk is not provided, authentication processing cannot be carried out, and extensible information cannot be acquired. Thus, extensible information can be reproduced with security.

摘要： Methods are provided for generating at least one translation table for a modem having a frame having a plurality of slots. DIL sequence information from another is used to generate ordered table of levels (15), and distances (20) between adjacent levels of the ordered table (15) found for each slot. The distances (20) are used to distinguish between slots subject to robbed bit signaling (RBS) and slots not subject to RBS (25), and the ordered tables (15) are used to make a determination as to whether the DIL sequence information is A-law or ν-law information. Scaling factors are generated from the A-law/ν-law determination as well as from a PAD estimation, and the scaling factors (80) are utilized in generating translation tables (100a, 100b). A PAD estimation function is utilized in finding the PAD estimation.
