摘要： An interactive method for composing an alphanumeric message by a caller using a telephone keypad includes storing (215) a lexical database (135) from which unigram probabilities, forward conditional probabilities, and backward conditional probabilities for a plurality of words can be recovered; storing a received sequence of key codes (405) representing a sequence in which keys on a telephone style keypad are keyed; generating a word trellis including candidate words (415) derived from the sequence and the lexical database; determining a most likely phrase (420) from the candidate words, the unigram probabilities, forward conditional probabilities, and backward conditional probabilities; generating a most likely message (425) from the most likely phrase and presenting the most likely message to the caller; and confirming that the most likely message is the alphanumeric message (430).

摘要： A paging system has a signal for transmitting a variable amount of messages to paging receivers. The signal has a synchronization signal, an address field, an information and a boundary signal indicative of the boundary between the address field and the information field. Each message has addresses which are included within the address field and may have message information which is included in the information field. The information field includes two portions, a first portion having a plurality of packets for holding a predetermined amount of information and a second portion for holding a variable amount of information. If the information associated with a message is less than the predetermined amount, the message information is stored in the first portion of the information field. If the message information is greater than the predetermined amount, it is stored in the first and second portions of information field and a vector signal indicating the location of the message information is stored in the first information field. The first portion further includes at least one check signal which provides parity for a plurality of packets. Methods of generating the message signal including a group message for a plurality of receivers, receiving a message including the group message, displaying a message and conserving power during the reception of a message are described.

摘要： A system controller (102) is for generating a compressed facsimile message in a radio communications system (100). The system controller (102) includes an image memory (203) for storing an optical image, means for image analysis (205), means for best scan angle identification (204), an image rotator (220), and a facsimile encoder (225). The means for image analysis (205) generates a long line analysis of a portion of the stored optical image using a scan angle. The means for best scan angle identification (204) identifies a best scan angle from one or more image analyses generated by the image analysis means (205). The image rotator (220) generates an aligned optical image by using the stored optical image and the best scan angle. The facsimile encoder (225) generates the compressed facsimile message from the aligned optical image.

摘要： A signalling system provides for efficient reception of message by a plurality of Earth based selective call receivers such as pagers. The signals are transmitted from satellites in orbit above the Earth. Each satellite includes a multiple lobe antenna capable of transmitting messages to a selected portion of the surface of the Earth. Methods for conserving satellite transmission power in the communication of message information are described. Furthermore, a signalling protocol transmitted by the satellite provides for power conservation by Earth based selective call receivers. Additionally, a method enabling an area of the Earth to receive messages from multiple satellites is described.

A transmitter section, responsive to the transmission control signals, transmits the coded message signals. Additional transmission control signals may also be derived from one or more receiver control signals embedded in the coded message signals.

摘要： A communication system includes a transmitter for transmitting messages to a plurality of receiving devices of the communication system, and a processing system. The processing system is adapted to convert a caller's voice message to a sequence of phonemes whereby the caller's voice message is intended for a receiving device. To accomplish the conversion, steps of Fourier transform, spectral subdivision, envelope filtering autocorrelation function determination of each subdivision, and voiceness determination for each subdivision are performed. The processing system is further adapted to generate a sequence of phoneme indexes and voice features corresponding to the sequence of phonemes, and to cause the transmitter to transmit the sequence of phoneme indexes to the receiving device for generating a voice signal representative of the caller's voice message. The voice features can include spectral features, average energy, duration, and pitch to improve the quality of the voice signal. The receiving device can be a selective call radio.
