Abstract
A 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 is provided, wherein each OFDM symbol is modulated by a predetermined number of encoded bits. The Dual Carrier Modulator comprises a grouping unit for grouping Nencoded bits of a serial bit stream into bit groups each having a predetermined number of bits. The Dual Carrier Modulator also comprises a mapping unit for mapping each bit group received from said grouping unit to complex symbols using an orthogonal transform. The Dual Carrier Modulator further comprises a reordering unit for reordering the complex symbols mapped by said mapping unit. Each complex symbol is provided to modulate a corresponding data tone of an OFDM symbol.
