Abstract

Dual Carrier Modulator (DCM) for a Multiband OFDM (Orthogonal Frequency Division Multiplexing) Transceiver of a Ultra Wide Band (UWB) wireless personal access network transmitting OFDM modulated symbols, wherein each OFDM symbol is modulated by a predetermined number (NCBPS) of encoded bits, said Dual Carrier Modulator (1) comprising: (g) a grouping unit (1-1) for grouping NCBPS encoded bits of a serial bit stream into bit groups each having a predetermined number (m) of bits; (h) a mapping unit (1-2) for mapping each bit group received from said grouping unit to complex symbols(y) using an orthogonal transform; and (i) a reordering unit (1-3) for reordering the complex symbols (y) mapped by said mapping unit, wherein each complex symbol (y) is provided to modulate a corresponding data tone of an OFDM symbol.
