Analytical and practical evaluation of diversity penalties in multi-bit-rate coherent FSK systems


Fully analytical expressions are presented for calculating the bit-error-rate (BER) and sensitivity penalties in frequency-shift-keying (FSK) receivers with noncoherent square-law IF detection. With these results one can directly compute the sensitivity and diversity penalties as a function of the IF filter bandwidth. Postdetection filtering is included in… (More)
