Abstract
This paper presents a flexible architecture suitable for concurrent processing of multiple radio standards. The proposed architecture is based on a coarse-grained reconfigurable cell array, consisting of distinct processing and memory cells. Flexibility of the architecture is demonstrated by performing a coarse time synchronization and fractional frequency offset estimation for multiple OFDM standards. The radio standards under analysis are IEEE 802.11n, LTE, and DVB-H. The reconfigurable cell array, containing 2-by-2 cells, is capable of processing two concurrent data streams from the standards. Dynamic reconfigurability of the architecture enables run-time switching between the standards. The implemented 2-by-2 cell array is synthesized... (More)
This paper presents a flexible architecture suitable for concurrent processing of multiple radio standards. The proposed architecture is based on a coarse-grained reconfigurable cell array, consisting of distinct processing and memory cells. Flexibility of the architecture is demonstrated by performing a coarse time synchronization and fractional frequency offset estimation for multiple OFDM standards. The radio standards under analysis are IEEE 802.11n, LTE, and DVB-H. The reconfigurable cell array, containing 2-by-2 cells, is capable of processing two concurrent data streams from the standards. Dynamic reconfigurability of the architecture enables run-time switching between the standards. The implemented 2-by-2 cell array is synthesized using a 65 nm low-leakage standard cell CMOS library, resulting in an area of 0.479mm2 and a maximum clock frequency of 534MHz. High flexibility offered by the reconfigurable cell array allows the adoption of different algorithms onto the same platform. (Less)
