Abstract
In a method of receiving messages transmitted by radio in the form of coded characters, there is included storing a message in blocks together with error indications pertaining to the same, storing the same repeated messages in a register, and then combining a final version of the message from the blocks associated with the stored messages and containing the least number of errors. For guidance in the combination of blocks from different messages, there is an identity code inserted in each message. There are further included inserting, and searching for, characters in the messages pertaining to repetititon of the messages, the number of blocks in the messages and joining several messages into a continuous message. A receiver for carrying out the method contains a receiver aerial, a radio section, a demodulator, a decoder for the receiver's address, and a signal processor, which in turn contains a register for a message, a message memory for one or more messages, an error detector, the indications from which are also stored in the register, and a combination logic for combining a final version of the message from associated blocks containing the least number of errors.
