More Information
Summary:A transmitting apparatus in a CDM(Code Division Multiplexing) wireless communication system using OOK(On-Off Keying) and a transmitting method thereof are provided to improve an autocorrelation characteristic by using a Barker code and to improve a cross correlation characteristic so as to be applied to a plurality of piconets by using the Kronecker product of a unipolar code(prime code). A transmitting apparatus in a CDM wireless communication system using on-off keying is comprised of a DC offset part(31), a Barker code creation part(32), a multiplier(33), a unipolar code creation part(34), a Kronecker product operator(35), and a modulation part(36). The DC offset part(31) converts digital transmission data into bipolar data. The Barker code creation part(32) creates a Barker code. The multiplier(33) multiplies the bipolar data by the Barker code. The unipolar code creation part(34) creates a unipolar code. The Kronecker product operator(35) outputs the product of the unipolar code by output of the multiplier(33). The modulation part(36) modulates output of the Kronecker product operator(35) in an OOK method.
