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： A system for a direct digital down conversion of a 10.8 MHz intermediate frequency signal in the personal handy phone system. The present invention includes a system that enables a direct digital down conversion of a 10.8 MHz intermediate frequency signal into a digital baseband signal within cell stations and portable stations of the personal handy phone system. To perform this direct digital down conversion of a 10.8 MHz intermediate frequency signal, one embodiment of the present invention uses a hard limiter circuit, a sampler circuit and a digital down converter circuit. The hard limiter circuit of the present invention receives a 10.8 MHz intermediate frequency signal, utilized within cell stations and portable station of the personal handy phone system, and provides a threshold for it. The sampler circuit uses a 19.2 MHz oscillating clock signal to sample the intermediate frequency signal that is output from the hard limiter circuit. Due to spectral leakage, the 10.8 MHz intermediate frequency signal that was input into the sampler circuit is output as an 8.4 MHz intermediate frequency signal. The digital down converter circuit uses an 8.4 MHz signal to perform a digital down conversion of the 8.4 MHz intermediate frequency signal into a digital baseband signal. The present invention provides a system that utilizes only one digital down conversion stage to perform a direct digital down conversion of a 10.8 MHz intermediate frequency signal into a digital baseband signal.

摘要： A method and system that enables an automatic delay setting within a wireless local loop system. The present invention determines the transmission distance time delay existing between a base station and a personal station by employing the communication interface that is utilized between them. The main reason for determining the transmission time delay caused by large transmission distances (e.g., over 300 meters) existing between base stations and personal stations is to compensate for it. Once the transmission distance time delay is known, the personal station utilizes that value to compensate for it. Specifically, the present invention directs a base station to transmit a control signal to a personal station. The personal station receives the control signal and transmits a signal to the base station. The base station determines if it started to receive the signal from the personal station later than it expected the signal to arrive, assuming close proximity of the two stations. If the signal arrived when it was expected to arrive, the base station discontinues determining the transmission distance time delay. If the signal arrived later than expected, the base station calculates the time difference between the expected arrival time and the actual arrival of the signal. The time difference is equivalent to the transmission distance time delay. Once the time difference is determined, the base station then transmits it to the personal station. The personal station stores the transmission distance time delay value enabling it to compensate for it.

摘要： A method and system that enables a portable station within the personal handy phone system (PHS) to utilize the preamble field of the communication interface to contain extended common access channel field information while optimizing power consumption. The present invention can operate within a cell station of the PHS. The present invention empowers a portable station to identify the type of data contained within the preamble field. A predetermined number of data bits are extracted from the beginning of the preamble field of an incoming data frame received by a portable station. The present invention determines if the extracted data bits are identical to a predetermined data bit pattern. If the extracted data bits are identical to the data bit pattern, the portable station is directed to treat the data contained within the preamble field as the standardized preamble of the PHS by not storing it within memory and not performing a cyclic redundancy check (CRC) on it. If the data bits are not identical to the data bit pattern, the portable station treats the data contained within the preamble field as extended common access channel data by storing it within memory and performing a CRC on it. By enabling a portable station to identify the data within the preamble field, data storage and CRC are not performed on preamble data resulting in conservation of portable station power. Optimizing power consumption within a portable station is critical because it operates under limited battery power.
