Abstract:
A wireless telecommunications system that mitigates infrasymbol interference due to Doppler-shift and multipath and enables multiple access in one radio channel. Embodiments of the present invention are particularly advantageous for wireless telecommunications systems that operate in high-mobility environments, including high-speed trains and airplanes.

Claim (Index 1):
A base station apparatus, comprising:\n a processor configured to: transmit:\n (a) a first command to a first wireless terminal to transmit, into a radio channel during a superframe, a first modulated radio-frequency carrier signal that is modulated with:\n (i) a first waveform \u03c61(m1,n1) of a first waveform array \u03a61 and a first data item, and \n (ii) a second waveform \u03c62(m2,n2) of a second waveform array \u03a62 and a second data item, and \n \n (b) a second command to a second wireless terminal to transmit, into the radio channel during the superframe, a second modulated radio-frequency carrier signal that is modulated with:\n (i) a third waveform \u03c61(m3,n3) of the first waveform array \u03a61 and a third data item, and \n (ii) a fourth waveform \u03c62(m4,n4) of the second waveform array \u03a62 and a fourth data item, and \n \n wherein:\n (i) the waveform \u03c61(m1,n1) is partitioned into N1 time slots, and \n (ii) the waveform \u03c62(m2,n2) is partitioned into N2 time slot, and \n (iii) time slot p1 of the waveform \u03c61(m1,n1) comprises a basic waveform b1(m1) multiplied by exp [2\u03c0(n1\u22121)(p1\u22121)i/N1], and \n (iv) time slot p2 of the waveform \u03c62(m2,n2) comprises a basic waveform b2(m2) multiplied by exp [2\u03c0(n2\u22121)(p2\u22121)i/N2], and \n (v) time slot p3 of the waveform \u03a61(m3,n3) comprises a basic waveform b1(m3) multiplied by exp [2\u03c0(n3\u22121)(p3\u22121)i/N1], and \n (vi) time slot p4 of the waveform \u03c62(m4,n4) comprises a basic waveform b2(m4) multiplied by exp [2\u03c0(n4\u22121)(p4\u22121)i/N2], and \n (vii) the waveform \u03c61(m1,n1) is multiplied by the first data item, and \n (viii) the waveform \u03c62(m2,n2) is multiplied by the second data item, and \n (ix) the waveform \u03c61(m3,n3) is multiplied by the third data item, and \n (x) the waveform \u03c62(m4,n4) is multiplied by the fourth data item, and \n (xi) M1, N1, M2, and N2 are positive integers greater than 1, and \n (xii) m1 and m3 are positive integers in the range m1, m3\u2208{1, . . . , M1}, and \n (xiii) m2 and m4 are positive integers in the range m2, m4\u2208{1, . . . M2}, and \n (xiv) n1, n3, p1, and p3 are positive integers in the range n1, n3, p1, and p3\u2208{1, . . . , N2}, and \n (xv) n2, n4, p2, and p4 are positive integers in the range n2, n4, p2, and p4\u22081, . . . , N2}, and \n (xvi) M1\u2260M2; \n \n receive, from the radio channel during the superframe, a third modulated radio-frequency carrier signal via an antenna; demodulate the third modulated radio-frequency carrier signal to recover the first data item, the second data item, the third data item, and the fourth data item; and transmit, on an interface to a cellular infrastructure, the first data item and the second data item in association with the first wireless terminal and the third data item and the fourth data item in association with the second wireless terminal.
