Abstract
A method of transmitting convolutionally encoded data with separate, independent and looped encoding over at least one data portion. The data is distributed over one or more cycles, and a plurality of cycles can be grouped into packets for discontinuous transmission if necessary. Weighted decoding is effected independently and cycle by cycle: it starts at a robust location, with a relatively high likelihood, and terminates at a weak location, with a weak likelihood, ignoring the concept of time. This limits the size of the packets of errors and prevents the propagation of packets of errors due to scrambling. Independent encoding and decoding of data can be effected without exchanging parameters between cycles and the parameters of each cycle (size, redundancy, constraint length) can be separate. Different degrees of protection and time-delay are permitted as a function of the nature of the data to be transmitted (voice, digital data, signaling, etc.).
