Abstract:	One of the most challenging problems in astronomy today is to search for reionization of the neutral hydrogen (HI), which is expected to occur somewhere between redshifts of about 6 to 20. The reionization is likely to result in spatial and spectral fluctuations in emission and absorption in the redshifted 21cm radiation of several milli-Kelvin (mK) in the frequency range of about 100 to 200 MHz. Also there is expected to occur a gradual step of few mK in the global 21cm radiation. Here we discuss various search strategies.
