Parallel MIMO Turbo Equalization

Although the use of filter based equalizer with Multi Input Multi Output (MIMO) turbo equalization ensures promising error rate performance at low area overhead, it adds to the latency already imposed by turbo decoding. In this letter, in order to address the ever increasing requirements of high throughput and low latency, two parallelism techniques are proposed and analyzed for MIMO turbo equalization. Results demonstrate that significant speed gain and parallelism efficiency can be attained for different MIMO Spatial Multiplexing (SM) configurations without degrading the error rate performance.
