Abstract:
1. A packet processing method used in a wireless communication, comprising the steps of: a) running a modulo operation for a message to obtain a first modulus, the message including a set of first data and multiple second data; b) joining said multiple second data and said first modulus to run a logical operation with said first data to obtain a first logic data; c) transmitting said first logic data as a packet to a wireless receiver, receiving said packet at said wireless receiver, said wireless receiver having built therein a database containing a plurality of reference data; d) selecting one reference data from said database to run a logical operation with data formatted in the received packet to obtain a second logic data; e) joining the selected reference data and said second logic data to run a modulo operation to obtain a second modulus; and f) determining the selected reference data to be the same as the first data and the second logic data in step e) containing said multiple second data when said second modulus is zero; g) wherein said modulo operation employed during step a) and step e) is a cyclic redundancy check; h) wherein the degree of a generator polynomial provided to the cyclic redundancy check during step a) and step e) is greater than or equal to the number of bits of said first data and said multiple second data.
