VARIABLE RATE CODING FOR ENABLING HIGH PERFORMANCE COMMUNICATION

摘要

A protocol for optimizing the use of coded transmissions such as over wireless links. In this technique, interframes are split into segments selected to be an optimum size according to transmission characteristics of the radio channel. The inverse process is applied at the receiver. Using this scheme, segments containing erroneous data may be resent.

主权项

1. A code division multiple access (CDMA) subscriber unit comprising:
a protocol device, operatively coupled to a transceiver and an antenna, configured to produce packets and to segment the packets to produce a plurality of segments, wherein each segment includes a first field, a second field and a third field, wherein the first field includes an indication of whether the third field includes control or traffic data, the second field includes a sequence number of the segment, and the third field is a data field including data of the packet; the protocol device is further configured to combine segments of the plurality of segments into a block and to forward error correction (FEC) code the block; the protocol device is further configured to spread the FEC coded block using at least one CDMA code; and the transceiver and antenna are configured to transmit the spread FEC coded block.
