Abstract
This paper presents an implementation of channel estimation for LTE downlink MIMO system on a multi-core processor platform. With the development of wireless communication, it is gradually difficult for ASIC baseband processing solutions to adapt the rapidly changing communication requirements. Multi-core solution for communication applications arises due to its programmability and reconfigurability. The multi-core processor platform is a mesh array of SIMD cores which is well suited for communication applications. A channel estimator with the throughput of 113.5Msymbol/s is realized by fully utilizing task-level parallelism, data-level parallelism and pipeline structure on multi-core processor platform.
