Finite-length delay-optimized multi-input multi-output (MIMO) equalizers that optimally shorten the impulse response memory of frequency-selective MIMO channels are derived. The MIMO equalizers are designed to minimize the average energy of the error sequence between the equalized MIMO channel impulse response and an MIMO target impulse response (TIR) with shorter memory. Two criteria for optim...

Distributors and channels of distribution have existed since time immemorial. Channels of distribution have existed to get products to consumers cheaper, faster, and more effectively. Distribution encompasses various types of activities, depending on the type of and point in the supply chain where value is added. A supply chain constitutes a set of activities ranging from production and manufac...

Even before the current covid-19-pandemic, online grocery retailing in Germany is achieving a high level of momentum, giving rise to new and increasingly hybrid forms operation distribution models retail sector. These operational complementary, pure combined e-commerce are accompanied by spatial changes individual value-added steps, e.g. areas logistics, store structure transfer goods, which ha...
