CONVERSION METHOD OF TRANSMITTING AND RECEIVING WEIGHTING VALUE IN THE INTELLIGENT ANTENNA SYSTEM

摘要

A method of determining transmitting weighting value based on the receiving weighting value of the antenna array and a conversion method of transmitting and receiving weighting value in the antenna array which combines RAKE receiving and transmitting diversity are disclosed. The method of determining transmitting weighting value includes following steps: the step of determining receiving and transmitting direction vector of the array antenna; the step of determining the relationship of the receiving and transmitting weighting value with the receiving and transmitting direction vector of the array antenna according to the principle of minimum variance of the receiving and transmitting beam pattern, and the step of determining the conversion matrix of the receiving and transmitting weighting value in order to acquire the corresponding transmitting weighting value.
