Title: Digital voter for multi-site pst rf trunking system
Inventor: DERENGE CHARLES LEE
IPC: H04M11/00
Filed: 1990-04-05
Granted: 2000-02-22
Abstract: A digital voter system for a mulit-site public service trunking (PST) digitally trunked RF communications system operates on the principle that it is highly likely that messages received during a system redundancy removal period are redundant messages. For a given RF channel, digital receiver is associated with each of multiple sites and receives digital messages reported to it by its associated sites. The multiple digital receivers are connected to a digital selector via a service request line (FSL) and a serial data line (BSL). Digital receivers which have messages to transfer to to then digital selector attempt to seize the service request line and, if they successfully seize it, maintain the line in its seized state for the redundancy removal period. Digital receivers which have messages but discover the service request line is already seized simply discard their messages. Since it is likely that two digital receivers may successfully seize then service request line at or near the same time, a windowing technique is used to schedule the times different digital receivers may apply their messages to the serial data line. If a digital receiver sees signals on the serial data line before it is scheduled to begin transmitting, it discards its message and aborts its transmission attempt. The preferred embodiment voter thus handles messages very rapidly (to reduce system latency time) while effectively removing most redundant messages and reducing or eliminating data collision on the shared serial data bus.

Granted: 1993-11-09
Abstract: MULTI-LENGTH PACKET FORMAT INCLUDING           CHECK SEQUENCE(S) Abstract A unique packet transport word, i.e., header, format is disclosed which is advantageously employed to delimit the corresponding packet and to verify data fields in the transport word. An at least first parity check is employed in conjunction with a packet length indicator to delimit the corresponding packet. The at least first parity check is formed by computing a predetermined number of parity check bits from bits in predetermined bit positions of the transport word. These parity check bits are inserted into predetermined bit positions in the transport word. Similarly, bits representing the packet length indicator are also inserted into predetermined bit positions of the transport word. In a specific embodiment, a plurality of parity checks is employed to achieve increased robustness. The plurality of parity checks is formed such that each of the bits in predetermined bit positions of the transport word is used in computing at least two different parity check bits. In one embodiment, a first prescribed parity check is formed by computing parity over bits from predetermined bit positions in one or more groups of bit positions in the transport word and a second prescribed parity check is formed by computing parity over bits from predetermined similar bit positions in the groups of bit positions in the transport word. In one example, the transport word includes a plurality of bytes, each of which includes a predetermined number of bit positions forming columns and rows. Parity check bits forming the first prescribed parity check are obtained by computing parity from bits in predetermined bit positions in the transport word columns and parity check bits forming the second prescribed parity check are obtained by computing parity from bits in predetermined bit positions in the transport word rows. In this example, the first and second parity checks are obtained by so-called "group" processing and are adequate to both delimit the packets and verify the transport word data fields. These verified fields include, among others, the packet length and necessary information for delivery and "billing" of the packet. (FIG. 5).
