In this paper, the optimal spectral efficiency (data rate divided by themessage bandwidth) that minimizes the probability of causing disruptiveinterference for ad hoc wireless networks or cognitive radios is investigated.Two basic problem constraints are considered: a given message size, or fixeddata rate. Implicitly, the trade being optimized is between longer transmitduration and wider bandwidth versus higher transmit power. Both single-inputsingle-output (SISO) and multiple-input multiple-output (MIMO) links areconsidered. Here, a link optimizes its spectral efficiency to be a "goodneighbor." The probability of interference is characterized by the probabilitythat the signal power received by a hidden node in a wireless network exceedssome threshold. The optimized spectral efficiency is a function of thetransmitter-to-hidden-node channel exponent, exclusively. It is shown that fortypical channel exponents a spectral efficiency of slightly greater than1~b/s/Hz per antenna is optimal. It is also shown that the optimal spectralefficiency is valid in the environment with multiple hidden nodes. Alsoexplicit evaluations of the probability of collisions is presented as afunction of spectral efficiency.
