—Space-time codes from complex orthogonal designs (CODs) with no zero entries offer low Peak to Average Power Ratio (PAPR) and avoid the problem of switching off antennas. But square CODs for 2 a antennas with a + 1 complex variables, with no zero entries were discovered only for a ≤ 3 and if a+1 = 2 k , for k ≥ 4. In this paper, a method of obtaining no(More)
— Space-time codes from complex orthogonal designs (CODs) with no zero entries offer low Peak to Average power ratio (PAPR) and avoid the problem of turning off antennas. But CODs for 2 a antennas with a + 1 complex variables, with no zero entries are not known in the literature for a ≥ 4. In this paper, a method of obtaining no zero entry (NZE) codes,(More)
