Diversity Multiplexing Tradeoff Under Generalized Sampling Expansion
Abstract
Standard analysis of Single Input Multiple Output (SIMO) and Multiple Input Multiple Outout (MIMO) channels with N output signals assumes sampling each of the output signals at the Nyquist rate. Yet it is known from the Generalized Sampling Expansion (GSE) that for a SIMO channel a unique reconstruction of the input signal is possible when each output signal is sampled at 1/N the Nyquist rate. Also, from the Vector Sampling Expansion (VSE), it is known that fora MIMO channel with M input signals and N received signals, a unique reconstruction of the input signals is possible when each output signal is sampled at M/N the Nyquist rate, under the condition that N/M is an integer.
It is a common practice to evaluate fading channels by their Diversity Multiplexing Tradeoff (DMT).
In this work we calculate and analyze the optimal DMT of the 1xN GSE-sampled SIMO fading channel an achievable DMT for the MxN VSE-sampled MIMO channel.
