Watch this Time and Space Complexity of Algorithms from Intellipaat. What is Time Complexity? Time complexity is a measure of how fast a computer algorithm (a set of instructions) runs, depending on the size of the input data. In simpler words, time complexity describes how the execution time...
Space time coding arises from a technique known as diversity. MIMO system enables increased spectral efficiency. This paper presents the progress made towards determining the capacity and diversity benefits of multiple antennas under different assumptions about the underlying channel. Simulations suggest ...
A combined space–time block coding (STBC) and eigen-space tracking (EST) scheme in multiple-input-multiple-output systems is proposed. It is proved that the STBC-EST is capable of shifting hardware complexity from the receiver to the transmitter without any bit error rate (BER) performance lo...
Coping with time-selective fading channels is challenging but also rewarding, especially with multiantenna systems, where joint space-Doppler diversity and coding gains can be collected to enhance performance of wireless mobile links. These gains have not been quantified, and space-time coded systems ...
Programmers face complex decisions and coding tasks when coping with failure in distributed systems—especially when applications modify state that is shared across devices. Unfortunately, a lot can go wrong even in simple scenarios of passing messages between distributed services. Connectio...
We then describe two representative categories of space-time systems, namely, the BLAST system and the space-time block coding system, both of which have been proposed for next-generation high-speed wireless system. Signal processing techniques for channel estimation and decoding in space-time ...
