A technique is used in a data terminal (110, 160) that encodes and decodes a data packet that is transmitted in a link of a frequency hopping system. During encoding, an information portion of the data packet is determined for transmission, a transmit redundancy check code is generated over the information portion and an identifier using a predetermined redundancy check code generator, and the data packet is generated to include the transmit redundancy check code and the information portion, but exclude the identifier. During decoding, the information portion and a received redundancy check code of the received data packet are determined, a calculated redundancy check code is generated over the information portion and the identifier, using the predetermined redundancy check code generator, and the information portion is rejected when the received redundancy check code does not match the calculated redundancy check code.
A method for encoding a data packet that is transmitted in a link of a communication system from a first terminal to a second terminal, comprising in the first terminal the steps of:
