Abstract:
1. An iterative decoder, comprising: a plurality of servers which each perform the iterative decoding of a data block; an input buffer memory for temporarily storing the data blocks to be decoded by the servers; a control unit for allocating each data block to be decoded to a server; in which the number of iterations of the decoding procedure performed by each server is determined on the basis of a stopping criterion and the control unit allocates data blocks to be decoded to the various servers as and when they make themselves available, wherein: the input buffer memory comprises N+L memory locations, where N is the number of servers and L is the number of so-called additional locations; each block to be decoded which is received while all the servers are busy is stored in one of the L additional locations possibly available, or it is lost if the input buffer memory is entirely filled; and the number L of additional locations and the number N of servers are such that the probability P
