摘要: A canonical space-time characterization of mobile wireless channels is introduced in terms a fixed basis that independent the true channel parameters The captures essential degrees freedom received signal using discrete multipath delays, Doppler shifts, and directions arrival (DOA). representation provides robust propagation dynamics eliminates need for estimating delay, DOA different multipaths, Furthermore, it furnishes natural framework designing low-complexity receivers. Single-user receivers based on are developed analyzed, It demonstrated resulting deliver near-optimal performance at substantially reduced complexity compared to existing designs.
