Parallel MIMO Turbo Equalization
IEEE Communications Letters, 2011Although 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 ...
