In this paper, we develop a new low-complexity linear frequency domain equalization (FDE) approach for continuous phase modulated (CPM) signals. As a CPM signal is highly correlated, calculating a linear minimum mean square error (MMSE) channel equalizer requires the inversion of a nondiagonal matrix, even in the frequency domain. In order to regain the FDE(More)
We present a new symbol block construction which yields a cyclic continuous phase modulated (CPM) signal to enable frequency domain equalization. It is known that in addition to a cyclic prefix, a subblock of data-dependent symbols has to be inserted in each block to cope with the memory in the CPM signal. We propose a new subblock, called intrafix, valid(More)
Obtaining sufficient EVM in all four 1.76GHz bandwidth channels specified by IEEE 802.15.3c and the emerging 802.11ad high-data-rate wireless communication standards for modulations as complex as QAM16 is a challenge. Recently reported implementations are therefore restricted to just 1 or 2 channels [1]. Wireless applications often use digital low-power(More)
Short-range digital communications at 60GHz have recently received a lot of interest because of the huge bandwidth available at those frequencies. The capacity offered to the users could finally reach 2Gbps, enabling the deployment of new multimedia applications. However, the design of analog components is critical, leading to a possible high nonideality of(More)
The large bandwidth available at 60 GHz together with the resulting wavelength of only 5 mm allow the design of multi-gigabit/s wireless devices equipped with large arrays of tiny antennas. This enables wireless communication of large contents multimedia such as high-definition video. However, due to the high cost and power consumption of analog frond-end(More)
