摘要： The invention relates to a transmission system comprising a transmitter (100) which includes a coder for coding an information signal (11) into a digital signal (11, 12) constituted by the information signal (11) and a redundancy signal (12), the redundancy signal (12) being generated by way of a cyclic code from the information signal (11 ), and comprising a receiver (101) which includes a decoder with a storage unit (2) for storing the information signal (11) and with an error correction means which has an optionally feedback shift register (3) for processing the digital signal (11, 12). The transmission system is to make both the correction of burst errors as well as the correction of random errors possible in a single error correction means. There is proposed that the error correction means of the decoder comprises a burst error detection means (4) for producing a first error information signal (B) from predeterminable storage contents (S.sub.0 . . . S.sub.11) of the shift register (3) and a random error detection means (5) for producing a second error information signal (E) from the aggregate storage contents (S.sub.0 . . . S.sub.11) of the shift register (3), and that a control means (8) is provided for evaluating the first error information signal (B) and second error information signal (E) and combining means (E1) are provided for combining the storage contents (S.sub.0 . . . S.sub.17) of the shift register (3) with the storage contents of the storage unit (2). The transmission system may be used for example, in video communication systems.

摘要： A diversity receiver having at least two receive branches, and only one equalizer. Each receive branch includes a matched filter and circuits for forming an autocorrelation function for each estimated impulse response of the individual receive branches. A first adder circuit adds the output signals, weighted with weighting factors of the matched filters to form a first sum. A second adder circuit add the autocorrelation functions weighted with weighting factors to form a second sum. The weight factors are approximately inversely proportional to the instaneous noise power in each receive a branch. An equalizer evaluates the two sums.
