摘要： Voice recording and playback mode using the G.726 half-rate within the personal handy phone system (PHS). When a portable station within the PHS operates as a voice recorder (e.g., functioning as an answering machine), a cost effective system in accordance with the present invention is adapted to compress and store received voice/sound signals in order to increase the usage of limited memory resources provided within the portable station. The present invention also enables previously compressed and stored voice/sound signals to be decompressed and played back in various portable station playback modes. Specifically, the portable station receives a voice/sound signal in a full rate (e.g., 32 kilobits-per-second) 4-bit adaptive differential pulse code modulation (ADPCM) data format in compliance with the International Telecommunication Union (ITU) recommendation G.726. The present invention compresses this received voice/sound signal to a half rate (16 kilobit-per-second) 2-bit ADPCM data format in compliance with the ITU recommendation G.726 in order to increase the usage of the limited memory resources provided within the portable station. During a playback mode of the portable station, the present invention decompresses the previously compressed and stored voice/sound signal to facilitate its playback.

摘要： The present invention provides data communication devices, personal handy-phone system base stations, and methods of communicating data. One embodiment of the present invention provides a data communication device including: a transceiver operable to receive wireless signals and recover a baseband signal containing a plurality of first slots from the received wireless signals; a multiple access processor coupled with the transceiver, the multiple access processor being operable to extract data from the first slots and communicate data at a first information transfer rate; a data formatter operable to combine data from plural first slots to form a second slot, the data formatter further being operable to output the second slot at a second information transfer rate; and an interface coupled with the data formatter, the interface being configured for connection with a network and operable to communicate the second slot. Another embodiment of the present invention provides a method of communicating data including: forming a plurality of first slots containing data to be communicated; communicating the first slots including transmitting wireless signals and receiving the wireless signals; extracting the data from the wireless signals at a first information transfer rate following the receiving; combining data from plural first slots following the extracting; forming a second slot using the combined data; and outputting the second slot at a second information transfer rate.
