Abstract

See full text

The present invention comprises a method and apparatus for synchronizing data frames from a wide bandwidth data stream which is divided up and transmitted across a plurality of parallel channels in a mobile telephone system. Prior to transmitting the data frames, a transmit synchronizer synchronizes data frames aligned in the same position in different parallel channels by inserting a common bit from a repeating PN synchronization sequence into the aligned data frames. Upon receiving the data frames at a destination, a receive synchronizer extracts the synchronization bit from each data frame. A series of sequential bits from each parallel channel is compared against the original PN synchronization sequence to identify the position of each data frame relative to the other data frames and reconstructs the original wide bandwidth data stream.
