Abstract:
1. A method of performing Pseudo-Noise (PN) quadrature covering for transmitting data via an access channel by an access terminal, the method comprising: receiving an access long code mask MI generating a MI mask (In-phase mask) which is a mask sequence used for generating a PNI (In-phase pseudo-noise) sequence and a MQ mask (Quadrature-phase mask) which is a mask sequence used for generating a PNQ (Quadrature-phase pseudo-noise) sequence by the access terminal; generating the PNI and the PNQ which are sequences for the PN quadrature covering by the access terminal; and transmitting the data covered with the generated PNI sequence and the data covered with the generated PNQ sequence via the access channel by the access terminal, wherein the MI wherein MI wherein MI wherein ⊕ denotes exclusive OR operation, and wherein the PNI is a sequence summed by the MI mask and a PN sequence generated by a polynomial PI(x)=x
