A 14-Band Low-Complexity and High-Performance Synthesizer Architecture for MB-OFDM Communication

Abstract: This work presents a 14-band low-complexity and high-performance synthesizer architecture for multiband orthogonal frequency-division multiplexing operating in the range of 3.1 to 10.6 GHz. The synthesizer uses a single phase-locked loop with trivial divide-by-2 circuits, single side band mixers, low-complexity filters, and multiplexers. Specifications of the synthesizer components are chosen in order to minimize the total spurs power and respect the IEEE802.15.3a recommendations.Index Terms-Frequency synthesi… Show more

“…However, the required frequency synthesizer can suffer from high complexity, as it needs to fulfill the constraints necessary to avoid interference between the users. Based on the example of the MB-OFDM (multi-band OFDM) standard [12] with very strict constraints, we have studied and developed an agile frequency synthesizer, able to switch between 14 frequency bands between 3.432 and 10.296 GHz [13]. It requires only one phase locked loop (PLL); the frequencies are generated by consecutive mixing and selection between different outputs of the PLL.…”

“…There are several studies that have been made for multiple CW generation; in [3]a method for generating four CW signals is elaborated with the expense of using four digital signal generators. In [4] 14 consecutive frequency bands are generated at multiples of 528MHz, which might be suitable, with some modifications, only for the case of intra-band CA. Also, in [5]a method for generating coherently phased multiple tones for measuring linear responses over finite bandwidths is proposed, in which an M-tone baseband signal b(t) is created and modulated on the carrier frequency fc:…”
