摘要： A cellular radio-telephone system has a plurality of cells each of which has S sectors. The cells are grouped into a plurality of clusters each of which has N adjoining cells. Each cell has a set of assigned system frequencies with respective frequency subsets assigned to its sectors so that N groups of co-channel cells exist with each co-channel cell group including one cell from each cluster having channel frequencies corresponding to those for its co-channel cell group. Respective base station antennas are located in the respective sectors of the respective cells, and each of the cell sectors has a plurality of subscriber station directional antennas disposed at predetermined locations within the sector for communication linkage with the associated base station antenna. The cells are generally formed in rows and columns and further are formed to provide a predetermined relative orientation pattern for co-channel cell sectors. Co-channel cells form a first cell tier around a preselected center co-channel cell with a common direction operative as a reference orientation direction for co-channel sectors therein. Co-channel sectors in successive co-channel cells about the first tier being successively oriented in alternating first and second directions with sectors rotated by at least one sector rotation from the reference direction in the clockwise or counter-clockwise direction.

摘要： A vestigial identification system is provided for transmitting information in a cellular communications network employing frequency reuse. The vestigial identification system enables a receiver to detect both bit errors and interfering messages to avoid call disruption. A composite parity check is produced by encoding message data and a site identifier via an encoder. A transmitter conveys a code word, formed at a code word generator by combining the composite parity check with the message data, to a receiver. At the receiver, an encoder forms an error detection parity check by encoding both the message data from the code word and the site identifier. An error detector compares the composite parity check from the transmitted code word to the error detection parity check, and generates an error if the parity checks are not identical to one another, enabling rejection of the message by the receiver.

摘要： A cellular base station receiver uses a digital signal processor to decode receiver code words in an inner Reed-Solomon code. A list of code word estimates is generated by making different symbol erasure combinations. An outer cyclic redundancy code operates as an error detector for the word estimates. When a code word estimate is found to be error-free, it is accepted for output.

摘要： An approach for electronically performing beam steering is disclosed. For electronic scanning, an n-bit quantized phase shifting approach is employed at each array element of a phased array antenna. By applying an initial phase bias, either deterministically or randomly, in each of the array elements, the performance of a phased array with n-bit quantization (even with n=2) approaches the performance of a system with no quantization. This approach can be used with linearly polarized or circularly polarized waves. For circularly polarized waves, the 2n phase shifts required of n-bit quantization are achieved in a manner that provides a simple, low-loss construction, which allows production of a low-cost reflectarray or a flat-plate lens.

摘要： A mobile telephone system multiplexes plural voice traffic channels on a single carrier using a TDMA protocol. The capacity of the mobile telephone system is increased by assigning voice traffic capacity, not on a conversation basis, but on a speech spurt basis. In order to avoid compromising the voice transmission capacity, control signals (for the allocation and deallocation of both forward and reverse traffic channels) are sent using multiple diversity, i.e. both time and frequency. In addition, to increase the number of available control channels, a control channel comprises a sub-divided portion of an otherwise equivalent voice traffic slot. For reverse allocation requests, which are transmitted over a contention access channel, power diversity is used in addition to time and frequency diversity.
