摘要： A method for determining the position of a mobile station within a cellular telephone system having a plurality of cells. Voice information signals are transmitted between a first base station transmitter and a mobile station on a transmission channel. Thereafter, transmissions from the first base station transmitter of voice information signals on the transmission channel are ceased for a predetermined period of time. During the predetermined period of time when transmissions of voice information signals from the first base station transmitter have ceased on the transmission channel, the mobile station makes positional measurements. The position of the mobile station is determined in accordance with the positional measurements.

摘要： A system and method for reducing radio frequency interference arising in connection with pulsed transmission over time division multiplexed communication channels. In a first embodiment, a subscriber station is nominally assigned all of the slots of each frame of a first transmit channel. By transmitting RF energy substantially continuously, the subscriber station reduces interference arising from pulsed transmission. In a second embodiment, a subscriber station is nominally assigned one or more slots of each frame of a primary channel for conventional transmission of useful information, and is also instructed to continuously transmit RF energy over an auxiliary channel at times other than during the assigned primary channel slots. In this way, interference generated in the vicinity of the subscriber station is reduced due to the substantially continuous transmission of RF energy by the subscriber station. More than one subscriber station may simultaneously utilize the auxiliary channel during reduced interference mode operation.

摘要： A code division multiple access (CDMA) communication system in which cellular techniques are utilized in a wireless Private Branch Exchange (PBX) environment. A microcellular arrangement is defined in which a base station communicates user information signals using CDMA communication signals with subscriber terminals. A distributed antenna system is utilized in the system to provide multipath signals which facilitate signal diversity for enhanced system performance.

摘要： A message communication system employing one or more centralized communication stations transmitting messages through Earth orbit relay satellites to mobile receivers utilizing Time Division Multiplexed (TDM) communication signals having signal time frames divided into a series of transmission channels. A predetermined number of the channels are designated as address channels with the remainder being used for data transfer. Information transmitted on the address channels is used by receivers to determine both the presence of a message and its corresponding data transmission channel. Each system receiver scans, and tracks only the communication signal address channels until a message addressed to that receiver is detected, at which time the selected receiver changes channels to the designated data channel for reception of the message. Thus, demodulation of the entire communication signal is not required and processing time and power is reduced for the typical waiting condition when messages are not being received. While a message is being received only a portion of the communication signal need to be received, demodulated and decoded. The decoded message is then displayed on a display screen or similar device for the recipient.
