Abstract EN
This paper presents a flexible interleaver architecture supporting multiple standards like WLAN, WiMAX, HSPA+, 3GPP-LTE, and DVB.
Algorithmic level optimizations like 2D transformation and realization of recursive computation are applied, which appear to be the key to reach to an efficient hardware multiplexing among different interleaver implementations.
The presented hardware enables the mapping of vital types of interleavers including multiple block interleavers and convolutional interleaver onto a single architecture.
By exploiting the hardware reuse methodology the silicon cost is reduced, and it consumes 0.126 mm2 area in total in 65 nm CMOS process for a fully reconfigurable architecture.
It can operate at a frequency of 166 MHz, providing a maximum throughput up to 664 Mbps for a multistream system and 166 Mbps for single stream communication systems, respectively.
One of the vital requirements for multimode operation is the fast switching between different standards, which is supported by this hardware with minimal cycle cost overheads.
Maximum flexibility and fast switchability among multiple standards during run time makes the proposed architecture a right choice for the radio baseband processing platform.
