  We will investigate practical aspects for a recently introduced blind
(noncoherent) communication scheme, called modulation on conjugate-reciprocal
zeros (MOCZ), which enables reliable transmission of sporadic and short-packets
at ultra-low latency in unknown wireless multipath channels, which are static
over the receive duration of one packet. Here the information is modulated on
the zeros of the transmitted discrete-time baseband signal's $z-$transform. Due
to ubiquitous impairments between transmitter and receiver clocks a carrier
frequency offset (CFO) will occur after a down-conversion to the baseband,
which results in a common rotation of the zeros. To identify fractional
rotations of the base angle in the zero-pattern, we propose an oversampled
direct zero testing decoder to identify the most likely one. Integer rotations
correspond to cyclic shifts of the binary message, which we compensate by a
cyclically permutable code (CPC). Additionally, the embedding of CPCs into
cyclic codes, allows to exploit additive error correction which reduces the
bit-error-rate tremendously. Furthermore, we use the trident structure in the
signals autocorrelation to estimate timing offsets and the channels effective
delay spread. We finally demonstrate how these impairment estimations can be
largely improved by receive antenna diversity, which enables extreme bursty
reliable communication at low latency and SNR.
