The pairwise error probability analysis for the i.i.d. Rayleigh fading channel has led us to the product distance (for time diversity) and generalized product distance (for transmit diversity) code design criteria. Extend this analysis for the i.i.d. Rician fading channel.
1. Does the diversity order change for repetition coding over a time diversity channel with the L branches i.i.d. Rician distributed?
2. What is the new code design criterion, analogous to product distance, based on the pairwise error probability analysis?
obtain the equations for the simplest 3 level AND -OR gate implementation of a 4 bit input circut that proudces an output of 1when the binary value of the input is Any prime number or AnyFibonacii number or both.
A half-wave dipole antenna in a PCS handset at 1.9 GHz, requires a signal strength of 0.01 micro volts per centimeter to operate with acceptable performance. The transmit antenna is assumed to be a half-wave dipole, has a cell radius of 5 km.
