Abstract: A method of communication for use, for instance, in systems such as solar panel power generation systems, house monitoring systems, traffic surveillance systems or smart street lighting systems may comprise:- providing a communication circuit (such as a modem 10) for communicating signals conveying information messages, the communication circuit (10) supporting a first communication protocol (101), adopting, for instance, S-FSK modulation, and a second communication protocol (102), adopting, for instance,PSK or QAM modulation,- including in the communicated signals first signals conveying first information messages and second signals conveying second information messages, wherein the first information messages comprise repetitive messages having fixed repeated content and the second information messages comprise non-repetitive messages having variable content, and- transmitting the first signals and the second signals via the communication circuit using the first communication protocol (101) for the first, repetitive signals and the second communication protocol (102) for the second, non-repetitive signals, respectively.

Abstract: In order to execute, as a function of a received signal (r), a procedure of channel estimation in a transmission channel with memory in a telecommunications system, there is envisaged an operation of estimation of a delay spread associated to said channel, said operation of estimation comprising calculation of a root mean square value ( τ rms ) of delay spread by means of a step of evaluation of crossings with a threshold level of a quantity associated to a transfer function of said channel. Said step of evaluation of crossings comprises evaluating a mean number of crossings ( λ 0 ) of the real and imaginary parts of said channel transfer function with a threshold level corresponding to the zero level. Preferential application is to OFDM telecommunications systems and in particular wireless. systems according to the IEEE 802.11a WLAN standard or the Hyperlanil WLAN standard.
